タンパク質混合試料の分離分析法として，一次元目に等電点電気泳動，二次元目にポリアクリルアミドゲル電気泳動を行う二次元電気泳動法が一般的に利用されている．しかしながら，従来法では煩雑な実験操作と長い分析時間を要するほか，多量の試薬を消費する点が課題であった．そこで本研究では，これまでに開発してきたデジタル電気泳動に関する知見を基に，異種機能性ゲルが二次元的に配置・集積された平板型カートリッジデバイスを開発した．モデルタンパク質を用いた基礎評価の結果，作製したデバイスと治具を用いた試料導入，デジタル分子ふるい電気泳動，及びpH緩衝ゲルを用いたデジタル等電点電気泳動がそれぞれ可能であることが確認された．さらに，複数のpH緩衝ゲル及び分子ふるいゲルが配置・集積されたカートリッジデバイスを用いた二次元デジタル電気泳動について検証した結果，同一デバイス内での連続的二次元デジタル分離が実証された．

標的分子に対する特異的結合能を示す配列を持つ核酸であるアプタマーは，抗体に代わる分子認識素子としての応用が期待される分子である．しかしながら，従来のアプタマー選抜法では煩雑な実験操作を10〜15サイクル繰り返す必要があるため，アプタマー関連研究におけるボトルネックとなってしまっている．本研究では，これまでに開発したミクロスケール電気泳動フィルタリングに基づくアプタマー選抜法を細胞外小胞マーカー（CD63）のアプタマー選抜へと応用した．その結果，簡便な電気泳動に基づく標的分子導入，核酸導入，結合した核酸の洗浄・回収からなるわずか1サイクルの選抜操作によって，CD63アプタマー候補が獲得された．また，等温滴定カロリメトリーの結果から，選抜されたアプタマー候補の一つがCD63に対する結合能を持ち，非標的分子のウシ血清アルブミンには応答しないことが確認された．

デジタル電気泳動法は、各種機能性ヒドロゲルに対する試料分子の通過・非通過を利用した分離・濃縮法として近年注目されているが、ヒドロゲル充填デバイス作製の煩雑さが大きな課題であった。そこで、本研究では、簡易デバイスを用いたデジタル電気泳動技術の開発と、機能性ヒドロゲルによるタンパク質の分離・濃縮評価のため、異種ポリアクリルアミドゲル連続充填キャピラリーデバイスを作製し、デジタル分子ふるい電気泳動の基礎評価を行った。その結果、プレポリマー溶液中アクリルアミド総濃度(%T)と通過・非通過タンパク質の分子量との相関が明らかとなった。また、濃縮効率評価の結果、最大で約180倍の高感度化が確認された。さらに、5、15、25%Tポリアクリルアミドゲル連続充填デバイスを用いたデジタル分子ふるい電気泳動によって、分子量が異なるタンパク質の分離と濃縮が同時に達成された。以上の結果から、作製したデバイスを用いた簡便・高分離能・高感度なデジタル電気泳動が実証された。(著者抄録)

Aptamers, single-stranded DNAs/RNAs with a strong and specific interaction towards a target molecule, have wide applications in the fields of medicine and biosensors. In conventional aptamer selection methods, it is difficult to obtain "preorganized" and/or "induced-fit" type of aptamers selectively. In this study, separation and fractionation of single-stranded DNAs with/without stable preorganized structures were carried out using capillary sieving electrophoresis. The fractionated DNAs showed different mobilities and thermodynamic stabilities of their secondary structures; this outcome is deemed to be necessary for the synthesis of novel aptasensors with a desirable sensing mechanism.

【化学センシングの方法論・デバイス開発の新展開】インクジェットプリンティングによる試薬固定化法を利用する1ステップバイオアッセイマイクロデバイスの開発

本研究では、インクジェットプリンティングを用いて一つのポリジメチルシロキサン(Poly(dimethylsiloxane)、PDMS)製マイクロ流路内に2種類の反応試薬を固定化した1ステップ均一系競合型バイオアッセイマイクロデバイスを開発した。インクジェットプリンターは試薬をナノリットルサイズの液滴として正確な量を位置選択的に吐出するため、互いに反応する2種類の試薬を混ざることなく微少空間内に独立して固定化できる。そのため、先行研究でデバイスを作製する際に課題となった、相互に反応する試薬を固定化した二つのマイクロ流路を精密に組み合わせる操作が不要となる。本研究ではその一例として、ビオチン固定化酸化グラフェン(BG)と蛍光標識ストレプトアビジン(F-SA)を1本のマイクロ流路内に固定してビオチンアッセイマイクロデバイスを試作し、基礎検討として試薬の固定化位置や試薬及び添加剤種の評価を行った。その結果、液滴を流路壁面寄りに吐出すると再現性よく流路底面の両サイドに試薬固定できること、添加剤としてトレハロースが適すること及び、試料導入操作のみでの1ステップ検出で、検出下限は0.68ng mL-1となり、先行研究と比較して約1/600倍改善することを明らかにした。(著者抄録)

© 2019 Elsevier B.V. Metal nanostructures have great potential for optical label-free biosensors based on localized surface plasmon resonance (LSPR). The sensitivity of a metal nanostructure-based label-free biosensor (i.e., plasmonic sensor) depends on its plasmonic properties, which suffer a decrease in sensitivity by energy losses in the metal material. Here, we demonstrate an approach to improve the plasmonic properties of metal nanostructures by controlling the carrier density in the base polymer material using titanium nitride (TiN). It is expected that the light energy absorbed by TiN is converted into excitons, and it will assist LSPs in the metal nanostructure; thus, the losses of the metal material are compensated by the excitons excited in TiN. We designed a TiN-contained polymer-metal/core-shell structured nanocone array (NCA), comprising TiN nanoparticles (NPs) in a polymer core and metal shell (Au or Ag), and realized improvement of the refractive index (RI) sensitivity of a label-free biosensor by optimizing the TiN-contained polymer composition. As a result, the TiN-contained polymer-metal NCA, with a TiN NP concentration of 10 wt% in the polymer core, had a 1.5-fold higher RI sensitivity than that of the same NCA without TiN NPs. The results of the resistance measurement of the metal surface with the TiN NP-contained polymer (10 wt%) under light exposure suggest the conversion of exposed light into LSPs of metal via TiN. It is suggested that plasmonic properties and sensor performances can be improved by the presented approach. Moreover, in DNA hybridization detection, an extremely low limit of detection of 117.5 fM was achieved.

Copyright © 2019 American Chemical Society. The refractive index sensitivity of a localized surface plasmon resonance (LSPR) sensor is correlated to an enhanced local electromagnetic (EM) field originating from noble metal nanostructures. Here, we demonstrated that extensive EM field enhancement by a gold (Au) nanocone array (AuNCA) allowed highly sensitive and label-free detection of biomolecules in the visible wavelength spectrum. The AuNCA consisted of a polymer core and an Au shell, which was fabricated by using simple and inexpensive nanoimprint lithography. Under LSPR excitation, AuNCA absorbs visible light of a specific wavelength and extensively enhances the EM field near its surface. It was shown that AuNCA had high refractive index sensitivity (417.5 nm/RIU) because of the large distribution of the enhanced EM field, covering a large surface of the NCA. Moreover, in DNA hybridization detection, a very low limit of detection of 161 fM was achieved, and 1-base mismatch DNA was successfully discriminated by using AuNCA.

© 2018 Elsevier B.V. In this study, we developed a novel particle-type material comprised of graphene and polyethylene glycol (PEG) to solve the slow response problem of the previously reported microdevice for single-step immunoassay. Characterization of these graphene/PEG hybrids (GPH) was carried out using a transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy, and fluorescence analysis. We found that PEG attached to graphene surfaces behave like molecular sieves to separate free fluorescently-labeled antibodies from antigen-bound antibody immunocomplexes. The free antibody is PEG-permeable and directly adsorbs onto the graphene surface, where fluorescence is quenched by fluorescence resonance energy transfer. On the contrary, immunocomplexes are PEG-impermeable; thus, as the concentration of the antigen increases, the concentration of PEG-impermeable immunocomplexes also increases; consequently, increasing the fluorescence intensity of the solution. After characterizing GPH, single-step immunoassay microdevices were prepared by separately immobilizing the GPH and fluorescently-labeled antibodies on two independent microchannel arrays and combining them. Finally, we tested the proposed immunoassay microdevices with various known concentrations of C-reactive protein (CRP), an inflammatory marker protein, and successfully measured CRP concentration within an approximate time of 2 min by monitoring the fluorescence intensity change.

© 2019 The Japan Society for Analytical Chemistry. In this work, ionic liquid materials composed of pH indicator dyes were synthesized and used as a plasticizer for a plasticized PVC membrane-based ion-selective optode. We chose several triphenylmethane dyes and synthesized ionic liquids with those by an ion-exchange procedure, and found that an ionic liquid composed of bromothymol blue (BTB) realized the highest ion-exchange ratio of approximately 100% (highest concentration of dye). The absorbance response of the PVC membrane using a BTB-based ionic liquid was decreased by ca. 37% using the repetitive introduction of acid and base solutions, and reached to exhibit a stable and reproducible response. The concentration of dye was 20~70-times higher than that of the conventional ones. In addition, the PVC membrane was applied for anion sensing based on the coextraction of protons and anions in aqueous solutions, and it was found that the ion selectivity followed the Hofmeister series. In the future, the present ionic liquid material is expected to be applied for highly-selective and sensitive ion-selective optodes by the modification of functional groups such as ion-recognition or reaction with the target molecule.

© 2018 In this study, we developed a polymer/TiO2 hybrid two-dimensional photonic crystal (2D-PhC) optical ion sensor that shows fluorescence enhancement based on the matching of the fluorescence wavelength and the confinable wavelength of a 2D-PhC. The polymer/TiO2 hybrid PhC was fabricated from a TiO2 pillar array, where the interspace was filled with a polymer containing a fluorescent dye. We developed a method of fabricating the TiO2 pillar array based on nanoimprint lithography using liquid phase deposition. The polymer/TiO2 hybrid PhC was fabricated on a poly(ethylene terephthalate) (PET) film. Thus, it can be easily cut because of its high flexibility and used for ion sensing applications. By using a fluorescent dye-containing polymer (poly(methyl methacrylate), PMMA) for the fabrication of the polymer/TiO2 hybrid PhC, the fluorescence intensity was drastically (25 times) increased. Subsequently, we used an ion-sensing polymer composed of plasticized poly(vinyl chloride) (PVC), a fluorescent dye, and ion recognition elements in the polymer/TiO2 hybrid PhC to enable its use as a highly sensitive ion sensor. As a result, the ion sensor based on the plasticized-PVC/TiO2 hybrid PhC exhibited four times greater fluorescence intensity compared with that based on the plasticized PVC without the PhC structure.

© 2018 by the authors. In this paper, we have proposed a polymer-based photonic crystal (PhC) resonator, with multiple sizes of cavities, and a waveguide to be used as highly sensitive optical sensor components. Properties of the proposed PhC were simulated by the finite-difference time-domain method, and the polymer-based PhC resonator and waveguide were fabricated on a photoresist (polymer) by electron beam lithography, which was prepared on an Au-layer-deposited Si substrate. We detected the resonant light that penetrated through the waveguide and was trapped in the PhC resonator. Optical characteristics of the fabricated PhC were evaluated by detecting the polymer layer deposition process by using the layer-by-layer (LbL) method to deposit polymer layers. As a result, by using an optimized design of a polymer-based PhC resonator with a long cavity (equivalent to a defect of three holes), the PhC structure changes caused by LbL deposition lead to changes in resonant light wavelength (peak shift: 5.26 nm/layer). Therefore, we suggest that a PhC resonator and a waveguide is applicable as an optical sensor.

The present method using PVA film as a sacrificial layer allowed successful immobilization of an intact PVC membrane using an ionic liquid-based dye on only the convex-shaped PDMS surface without any deformation or increase of the inhomogeneity. In addition, two different kinds of PVC membranes were successfully immobilized simultaneously toward multiplexed detection.

We fabricated a titanium dioxide (TiO<inf>2</inf>)-based photonic crystal (PhC) using liquid phase deposition (LPD) to develop highly sensitive optical biosensors. The optical characteristics of the PhCs in the visible region were sensitive to the change in the refractive index of the surrounding medium due to an antigen–antibody reaction; thus, applications using the optical biosensor are expected to be highly sensitive. However, a base material with a high refractive index is indispensable for the fabrication of the PhC. Here, TiO<inf>2</inf>, which has optical transparency in the visible region, was selected as the high refractive index base material. The present LPD method allowed fabrication using low-cost apparatus. Furthermore, the mild conditions of the LPD method led to formation of TiO<inf>2</inf>-based PhC with fewer crack structures. Finally, the anti-neuron-specific enolase antibody was immobilized onto the TiO<inf>2</inf>-based PhC surface, and 1–1000 ng/mL of the neuron-specific enolase antigen was successfully detected.

© The Royal Society of Chemistry. A single-step, easy-to-use enzyme immunoassay capillary sensor, composed of functional multilayer coatings, was developed in this study. The coatings were composed of substrate-immobilized hydrophobic coating, hydrogel coating, and soluble coating containing an enzyme-labeled antibody. The response mechanism involved a spontaneous immunoreaction triggered by capillary action-mediated introduction of a sample antigen solution and subsequent separation of unreacted enzyme-labeled antibodies and antigen-enzyme-labeled antibody complexes by the molecular sieving effect of the hydrogel. An enzyme reaction at the substrate-immobilized hydrophobic coating/hydrogel coating interface resulted in a protein-selective fluorescence response. An antigen concentration-dependent response was obtained for diagnostic marker protein samples (hemoglobin A1c (HbA1c), 7.14-16.7 mg mL-1; alpha-fetoprotein (AFP), 1.4-140 ng mL-1; C-reactive protein (CRP), 0.5-10 μg mL-1) that cover a clinically important concentration range. The successful measurement of CRP in diluted serum samples demonstrated the application of this capillary sensor. This journal is

The caspase-3 inhibitor assay, which is important for drug development was successfully integrated into a "single step" by solving the immobilization problem of enzymes with low activity. Here we used the soluble polyethylene glycol (PEG) coatings for enzyme immobilization to the concave-shaped PDMS surface, and substrate immobilization to the convex-shaped PDMS surface. Then these PDMS structures were combined to form a capillary-structure, which we call a combinable poly (dimethylsiloxane) (PDMS) capillary (CPC) sensor, enabling simultaneous immobilization of two different reactive reagents such as enzymes and fluorescent substrates. The present sensor was disposable, and the fluorescence response was simply obtained by introducing the sample solution by capillary action. The caspase-3 activity was able to be maintained at approximately 90% under -80 °C storage conditions even after 5 months. Importantly, the total reaction time was reduced from an hour to 3-5 min, and simultaneous acquisition of multiple data sets required to determine IC50 value was also successfully achieved using the CPC sensor array. © 2014 The Royal Society of Chemistry.

To enhance sensitivity and facilitate easy sample introduction into a combinable poly(dimethylsiloxane) (PDMS) capillary (CPC) sensor array, PDMS was modified in bulk and on its surface to prepare "black" PDMS coated with a silver layer and self-assembled monolayer (SAM). India ink, a traditional Japanese black ink, was added to the PDMS pre-polymer for bulk modification. The surface was modified by a silver mirror reaction followed by SAM formation using cysteine. These modifications enhanced the fluorescence signals by reflecting them from the surface and reducing background interference. A decrease in the water contact angle led to enhanced sensitivity and easy sample introduction. Furthermore, a CPC sensor array for multiplex detection of serum sample components was prepared that could quantify the analytes glucose, potassium, and alkaline phosphatase (ALP). When serum samples were introduced by capillary action, the CPC sensor array showed fluorescence responses for each analyte and successfully identified the components with elevated concentrations in the serum samples. © The Royal Society of Chemistry.

A facile preparation method of a disposable capillary biosensor immobilizing a plasticized poly(vinyl chloride) (PVC) membrane ion-selective optode containing a lipophilic pH indicator dye and an ionophore, and a dissolvable poly(ethylene glycol) (PEG) membrane containing an enzyme is developed. The method involves the sequential introduction of membrane cocktail solution followed by air introduction. Repeating this process allowed facile preparation of a capillary biosensor comprised of two layer structure, which can be used for single-step biosensing just by sipping the sample with capillary action. Here a urea biosensor was prepared as a proof-of-concept. © 2010 The Chemical Society of Japan.

A simple capillary enzymatic biosensor was developed. This was prepared by simply coating a dissolvable membrane containing enzyme/s on the inner wall of a square glass capillary. An easy measurement was carried out by capillary force sample introduction with concurrent enzyme release and a reaction with a certain substrate. Enzyme-release capillary (ERC) biosensors showed long-term storage stability of at least two weeks for a β-galactoside derivative and glucose. Moreover, this could be integrated on a capillary-assembled microchip (CAs-CHIP) to broaden its multiple analyte sensing potential for clinical diagnostic applications. 2009 © The Japan Society for Analytical Chemistry.

Single-drop analysis of two different real sample solutions (2 μL) while simultaneously monitoring the activity of two sets of ten different proteases on a single microfluidic device is presented. The device, called a capillary-assembled microchip (CAs-CHIP), is fabricated by embedding square glass sensing capillaries (reagent-release capillaries, RRC) in the polydimethylsiloxane (PDMS) lattice microchannel, and used for that purpose. First, the performance reliability was evaluated by measuring the fluorescence response of twenty caspase-3-sensing capillaries on a single CAs-CHIP, and a relative standard deviation of 1.5-8.2 (% RSD, n∈=∈5 or 10) was obtained. This suggests that precise multiplexed protease-activity sensing is possible by using a single CAs-CHIP with multiple RRCs embedded. Then, using a single CAs-CHIP, real sample analysis of the activity of ten different caspases/proteases in cervical cancer (HeLa) cell lysate treated and untreated with the cell-death-inducer drug, doxorubicin, was simultaneously carried out, and a significant difference in enzyme activity between these two samples was observed. These results suggested the usefulness of the CAs-CHIP in the field of drug discovery. © 2008 Springer-Verlag.

The experimental conditions of the sample delivery inside the reagent-release capillary-based capillary-assembled microchip (RRC-based CAs-CHIP) were optimized and the reagent release procedure in the RRC is discussed. Recently, our group introduced the basic concept of the "drop-and-sip" fluid handling technique (Anal. Chem., 2007, 79, 908). A microliter volume of sample solution is dropped on the inlet hole and is sipped into another hole, producing a sample plug flow in the main poly(dimethyl siloxane) (PDMS) channel, concurrently filling each sensing capillary that faces the main PDMS channel. However, the detailed evaluation of the successful sample delivery condition and the reagent release behavior in the RRC has not been fully discussed. Under our experimental conditions, ca. 0.6 - 2.4 s of sample plug-RRC contact time allowed the successful sample introduction into the RRC by capillary force without any reagent leakage or disturbance of the sample plug flow. On the other hand, reagent release behavior inside the RRC is governed by both convective and diffusive mass transport, which leads to a faster mixing time of the sample with reagents immobilized inside the RRC compared to that expected from the simple diffusion alone. 2008 © The Japan Society for Analytical Chemistry.

A general and simple implementation of simultaneous multiparametric sensing in a single microchip is presented by using a capillary-assembled microchip (CAs-CHIP) integrated with the plural different reagent-release capillaries (RRCs), acting as various biochemical sensors. A novel "drop-and-sip" technique of fluid handling is performed with a microliter droplet of a model sample solution containing proteases (trypsin, chymotrypsin, thrombin, elastase) and divalent cations (Ca2+, Zn2+, Mg2+) that passes through the microchannel with the aid of a micropipette as a vacuum pump, concurrently filling each RRC via capillary force. To avert the evaporation of the nanoliter sample volume in each capillary, PDMS oil is dropped on the outlet hole of the CAs-CHIP exploiting the capillary force that results in spontaneous sealing of all the RRCs. In addition, this high-speed sample introduction alleviates the possibility of protein adsorption and capillary cross-contamination, allowing a reliable and multianalyte determination of a sample containing many different proteases and divalent cations by using the fluorescence image analysis. Presented results suggested the possible application of this microchip in the field of drug discovery and systems biology. © 2007 American Chemical Society.

A capillary immunosensor is developed as a sensing unit of a capillary-assembled microchip (CAs-CHIP) that is geared towards simultaneous multiple immunoassay. It is prepared by subsequently treating the inner surface of a square glass capillary (internal dimension 50 μm) with 3-aminopropyltriethoxysilane -glutaraldehyde-protein A (APTES-GA-Protein A), which significantly reduced the non-specific adsorption. Consequently, accurate quantitative immunoassay measurement is demonstrated using human and chicken IgG as model samples, yielding a detection limit of about 1 ng mL-1 for both antigens with a total analysis time of about 60 min. The immunosensor also displayed interesting practical properties like long-term stability of at least a month at 10°C and minimal consumption of secondary labeled-antibody with one-million-fold dilution. It is expected that the integration of this fluorescent immunosensing unit into the CAsCHIP will enhance the analytical performance of the microchip through simultaneous multiple immunoassay in a single microfluidic device. This type of biochip may have a significant impact in clinical diagnostics and drug-screening applications.

A capillary-assembled microchip (CAs-CHIP), prepared by simply embedding square capillaries in a lattice polydimethylsiloxane (PDMS) channel plate with the same channel dimensions as the outer dimensions of the square capillaries, has been used as a diffusion-based pretreatment attachment in capillary electrophoresis (CE). Because the CAs-CHIPs employ square-section channels, diffusion-based separation of small molecules from sample solutions containing proteins is possible by using the multilayer flow formed in the square section channel. When a solution containing high-molecular-weight and low-molecular-weight species makes contact with a buffer solution, the low-molecular-weight species, which have larger diffusion coefficients than the high-molecular-weight species, can be collected in a buffer-solution phase. The collected solution containing the low-molecular-weight species is introduced into the separation capillary to be analyzed by CE. This type of system can be used for CE analysis in which pretreatment is required to remove proteins. In this work a fluorescently labeled protein and rhodamine-based molecules were chosen as model species and a feasibility study was performed. © Springer-Verlag 2006.

Measurement of binding constant by chip electrophoresis is a very promising technique for the high throughput screening of non-covalent interactions. Among the different electrophoretic methods available that yield the binding parameters, continuous frontal analysis is the most appropriate for a transposition from capillary electrophoresis (CE) to microchip electrophoresis. Implementation of this methodology in microchip was exemplified by the measurement of inclusion constants of 2-naphtalenesulfonate and neutral phenols (phenol, 4-chlorophenol and 4-nitrophenol) into β-cyclodextrin by competitive assays. The issue of competitor choice is discussed in relation to its appropriateness for proper monitoring of the interaction. © 2005 Elsevier B.V. All rights reserved.

Chemical syntheses using microchemical chips have been intensively investigated in recent years, but they have still not fully reached the stage of practical use. Combinatorial synthesis has been expected to be one of their useful applications. Benefits of using microchips, such as reduction in quantity of reagents and wastes, are thought to be suited for combinatorial syntheses, where numerous variations of products have to be synthesized each in small amounts. There are two modes of combinatorial syntheses using microchemical chips. One is sequential synthesis, in which reactant solutions are introduced sequentially in various combinations to a reaction microchannel. The other is parallel synthesis, where the number of reaction channels is the same as the number of final products, and starting materials are distributed to all the reaction channels in different combinations. Sequential synthesis has been considered as the more favorable way, because, especially when libraries of starting materials are large, numerous microchannels and complicated pipings for distribution of reagents to the channels are required for the parallel mode. Therefore, research on parallel microcombinatorial syntheses has been done only rarely, whereas there have been many reports of sequential microcombinatorial syntheses. Against this trend, our research group has taken an alternative path and tried to integrate both parallel reaction microchannels onto a glass microchip and channels for distributing reactant solutions to each reaction channel in a combinatorial mode. Microchips fabricated by laminating multiple layers of glass substrates have been used to construct three-dimensional microchannel networks necessary for mixing reagent flows in different combinations. We utilized low Reynolds number multi-phase laminar flow and developed micro-unit operations (MUOs). By combining MUOs in the multi-phase continuous laminar flows, microchemical systems were constructed. We called this micro-integration methodology "continuous-flow chemical processing (CFCP)", and by using it, a sequence of various operations in chemical syntheses could be integrated on a microchemical chip. Not just simple mixing of two reagents, which was most commonly done in microreactors, but also multi-step processes including other chemical operations, such as extraction and separation, could be carried out via CFCP. In the first part of this short review article, we explain CFCP with an example. Then, a microchemical chip with a three-dimensional microchannel network for a parallel reaction system is introduced. Finally, we present a case in which CFCP was realized in a three-dimensional microchannel network. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.

A recent microfabrication technology opened the new application field such as micro total analysis systems (Micro TAS) or microreactors. These systems employed physical characteristics provided by the liquid microspace, involving short diffusion distance, large surface to volume ratio, or small heat capacity. In contrast to these works, we focused on the chemical functions of highly-selective molecular recognition molecules or functional dyes of which we have been developed, to be integrated into microfluidic chemical sensing systems. The present paper describes our recent results concerning chemical sensing systems based on microfluidic devices. Here, a multi ion sensing system based on the intermittent reagent pumping and ion-pair extraction, a new biosensing scheme based on the enzyme-immobilized polymer membrane, and a novel multi ion sensing scheme based on capillary-assembled microchip, are presented. © 2005 The Japan Society for Analytical Chemistry.

This chapter provides information on micro and nano-fabrication technologies that have been introduced into chemical and biotechnologies. It also explains molecular and energy transport between multiphase laminar flow in a micro channel. As for chemical synthesis, micro reactors with sub-millimeter-sized micro channels are now eagerly investigated. Though there are some examples of electrokinetically-driven flow control in micro reactors, pressure-driven flow control is more commonly used for micro reactors. The aim is to develop methodology to integrate as many chemical processes as possible on microchips and to make full use of characteristics of micro space. Therefore, pressure-driven flow and developed techniques to operate chemical processing in pressure-driven laminar flow in micro channels are selected and for this microchips made of glass are used. Glass vessels are commonly used in many chemical experiments because of their chemical inertness and optical transparency. In order to realize these micro chemical systems based on multiphase laminar flow, some stabilization techniques for the multiphase flow has been inevitable. A micro channel with guide structures and surface modification to stabilize multiphase flows has been used. The chapter also presents a micro integration methodology, continuous flow chemical processing (CFCP), based on spontaneous motion of molecules in multi-phase laminar flow network in micro channel circuits. © 2003 Elsevier B.V.

In this paper, new "multiinformation dyes" (MIDs) with extended spectral sensitivity reporting on both changes in solvent polarity (solvatochromism) and in pH (halochromism) by changes in their visible absorption spectra, are presented. The merocyanine dyes 2,6-dibromo-4-[4-(1-dodecyl-4(1H)-pyridinylidene)-2-butenylidene]-2,5- cyclohexadien-1-one (KD-M301) and 2,6-dibromo-4-[4-(1-dodecyl-4(1H)-quinolinylidene)-2-butenylidene]-2,5- cyclohexadien-1-one (KD-M402) were designed, synthesized, and characterized regarding analytical applications. The spectral sensitivity for the MIDs was extended into the near-infrared (NIR) wavelength range (λmax = 800 nm in CHCl3 for KD-M402) and at the same time, the degree of solvent polarity-induced spectral shifts was strongly enhanced (Δλmax = 202 nm for KD-M402 between tetrahydrofuran (THF) and methanol), reaching similar values to the standard solvatochromic dye Dimroth-Reichardt's betaine on which the empirical ET(30) classification of solvent polarity is based. Compared to Dimroth-Reichardt's betaine dye, the molar absorption coefficient ε, is increased more than 10-fold (ε of KD-M402 in THF: 7.7 × 104 M-1 cm-1), allowing sensitive measurements at low concentrations of the dye. The dodecyl-substituted KD-M402 is suitable as a lipophilic pH indicator in ion-exchange type optical sensors (optodes) with optical detection in the near-infrared wavelength range. © 2003 Elsevier Science B.V.

Here we report a design and synthesis of a chemically functional polymer membrane by an interfacial polycondensation reaction and multilayer flow inside a microchannel. Single and parallel dual-membrane structures are successfully prepared by using organic/aqueous two-layer flow and organic/aqueous/organic three-layer flow inside the microchannel followed by an interfacial polycondensation reaction. By using the inner-channel membrane, permeation of ammonia species through the inner-channel membrane is successfully achieved. Furthermore, horseradish peroxidase is immobilized on one side of the membrane surface to integrate the chemical transform function onto the inner-channel membrane. Here substrate permeation through the membrane and subsequent chemical transformation at the membrane surface are realized. The polymer membrane prepared inside the microchannel has an important role in ensuring stable contact of different phases such as gas/liquid or liquid/ liquid and the permeation of chemical species through the membrane. Furthermore, membrane surface modification chemistry allows chemical transformation of permeated chemical species. These methods are expected to lead to development of complicated and sophisticated chemical systems involving membrane permeation and chemical reactions.

A new fluid flow inside the microchannel was successfully developed. The flow created here involves segmented flow injection of plural organic phases into a microchannel followed by contact with a single aqueous phase to form stable organic-aqueous two-layer flow inside the microchannel. Fundamental study on the developed flow inside the microchannel was performed by monitoring the dye-doped segmented organic phases by thermal lens microscopy (TLM). Excellent repeatability and very small injection volume in developing segmented flow were realized. The new fluid flow created here is expected to allow us multi-ion sensing, which is not easily demonstrated by conventional ion sensor technology using a solvent polymeric membrane, by combining with neutral ionophore-based ion pair extraction using plural numbers of organic phases containing different ionophore molecules.

An integrated multireactor system for 2 × 2 parallel organic synthesis has been developed on a single glass microchip. Three-dimensional channel circuits in the chip were fabricated by laminating three glass plate layers. The fabrication method is a straightforward extension of the conventional one, and topological equivalence for any three-dimensional circuits can be constructed easily with it. 2 × 2 phase-transfer amide formation reactions, which constitute a simple model for combinatorial synthesis, were successfully carried out on the microchip, and the integrity of the three-dimensional circuits was confirmed. Combinatorial chemistry with multi-microreactors, in conjunction with a high-throughput screening method based on μ-TAS technologies, is expected to provide an efficient tool for drug discovery.

A series of ionophores for ammonium ion-selective electrodes was designed and synthesized, and their characteristics were examined. The design of the ionophores is based on two different strategies: (1) introduction of bulky blocking subunits (decalino groups) in 20- or 21-membered crown ethers (TD20C6 and TD21C6), the ring size of which is expected to be suitable for selective NH4+ recognition, as compared to the slightly smaller K+; and (2) preorganized tripodal ionophores based on a 6-fold substituted benzene ring in order to complementarily recognize the tetrahedral NH4+, in contrast to the spherical K+. Compared to nonactin, a natural product that is used as a representative NH4+ ionophore, the newly developed TD20C6 showed higher NH4+ selectivity over K+ while retaining the selectivity over Na+(log KNH4+,K+pot≡ -1.5 and log KNH4+,Na+pot = -2.5). On the other hand, a tripodal ionophore with pyrazole nitrogen atoms as NH4+ binding sites showed high NH4+/K+. selectivity but suffered from increased Ca2+ interference (log KNH4+,K+pot = -2.1 and log KNH4+,Ca2+pot = -1.6). As an overall conclusion, the cyclic ionophores TD19C6 and TD20C6 are the best ammonium-selective ionophores developed to date.

Novel Mg2+ fluorescent molecular probes (KMG-20-AM and KMG-27-AM; where AM is an acetoxymethyl group) based on a coumarin possessing a charged β-diketone structure were designed and synthesized. These fluorescent probes produced a red shift from 425 to 445 nm in the absorption spectra after formation of a complex with Mg2+. The fluorescence spectra of these probes also showed a red shift from 485 to 495 nm and an increasing fluorescence intensity after formation of a complex with Mg2+. The optimum experimental conditions were excitation wavelength of 445 nm and a monitored wavelength of 500 nm, where these probes functioned as an indicator showing an image of increasing fluorescence in the presence of Mg2+. These probes showed a "seesaw-type" fluorescent spectral change with the isosbestic point at 480 nm due to the light excitation at 445 nm, which indicates that ratiometry can be used for the measurement. The molecular probes formed a 1:1 complex with Mg2+ and the dissociation constant (Kd) was 10.0 mM for KMG-20. The association constants of the probes with Mg2+ were ∼3 times higher than that with Ca2+, which showed that the selectivity of Mg2+ versus Ca2+ for these probes was over 200 times higher than that for commercially available Mg2+ fluorescent molecular probes such as mag-fura-2, Magnesium Green. As an application of these probes, intracellular fluorescent imaging of Mg2+ was demonstrated using a fluorescent microscope. After the addition of KMG-20-AM and KMG-27-AM into PC12 cells, a strong fluorescence was observed in the cytoplasm and a weak fluorescence in the nuclei region. After treatment with a high-K+ medium, the fluorescence intensity increased due to increasing intracellular Mg2+. The real image of Mg2+ release from the magnesium store was successfully observed with these Mg2+ fluorescent probes.

Thermal lens microscope (TLM) can be a powerful tool for a detection method for integrated chemistry laboratory (ICL). In spite of great potential of ICL, its application has been restricted due to the lack of highly applicable and sensitive detection methods. TLM developed by our group meets requirements of detection method for ICL, such as high sensitivity, high spatial resolution, and wide applicability. In this review, the principle and characteristics of TLM are introduced and usefulness of TLM in ICL is demonstrated in some analytical applications.

The preparation and response features of a micrometer-sized lithium ion-selective optode based on a liquid membrane were examined. The optode membrane was a plasticized poly(vinyl chloride) (PVC)-based copolymer incorporating a lipophilic 14-crown-4 derivative as the neutral lithium ionophore and a dibromofluorescein derivative as the fluorescent anionic dye. The detection mode was a fluorescence change based on the ion-pair extraction/ion exchange principle caused by the fluorescent anionic dye and the lithium ionophore. The 5-μm-sized microoptode was prepared by the micropipette fabrication method and characterized by measuring the optical responses to Li+ concentrations with the time-resolved photon counting method. The microoptode responded to lithium ion concentrations of ~0.5 to ~500mM. The micrometer-sized lithium ion-selective microoptode was successfully obtained when a tailed ionophore was used. The anchor effect of the tailed ionophore was useful for the lithium ion-selective microoptode to resolve leaching of the ionophore, which is a significant problem in a microoptode based on a liquid membrane. This demonstration indicates that other ion-selective microoptodes can be obtained simply by replacing the tailed ionophore. (C) 2001 Elsevier Science B.V.

Molecular transport across a water-organic liquid interface formed parallel to the side wall of a microchannel on microchips has been studied using methyl red as model compound and cyclohexane and n-octanol as organic solvents. The molecular transport was monitored by thermal lens microscopy and the kinetics of the process was studied for different concentrations and flow velocities. The influence of physico-chemical interactions between the model compound and organic solvents on liquid-liquid interface was demonstrated in the microspace and corresponding partition coefficients were calculated which confirmed the experimental results.

The structure of the formed complexes was elucidated by ESI-MS and 1H NMR spectroscopy. Deprotonation of the amide groups allows the receptors to form stable complexes with Hg2+. As an application of this neutral Hg2+ complex, an anion-selective electrode combined with a cationic additive is prepared, and exhibits an anti-Hofmeister selectivity pattern with enhanced selectivity for the iodide anion. The overall selectivity pattern of the electrode is I- > ClO4- > SCN- ≈ Br- > salicylate- > NO2- > Cl- > NO3- ≫ HCO3- > SO42- > F- > H2PO4-.

The preparation and response features of a micrometer-sized sodium ion-selective fiber optode based on a liquid membrane were described. The sensing membrane is a plasticized poly (vinyl chloride)-based copolymer with a neutral ionophore and an anionic dye. In order to fabricate a micrometer-sized fiber optode, a "micropipette fabrication method" was newly proposed to fix a liquid membrane-based optode on the small tip of an optical fiber probe. At the first stage of the investigation, it was found that the ionophore including a sodium ion in its cavity leached from the membrane phase. However, we have discovered that the problem can be resolved by using a "tailed" ionophore, which is an ionophore possessing a lipophilic long alkyl chain. The "'tail" of the ionophore functions as an "anchor", which prevents leaching of die ionophore from the membrane phase into the water phase. The anchor effect of the tailed ionophore was clearly demonstrated with 6 μm-sized sodium ion-selective optodes. In addition, the problem of fluorescence distortion due to photobleaching and solvent effect was resolved by a ratiometric calibration in which the sensor response is monitored by the spectral shift of the dual-emission fluorescence. The sensor response of an 8 μm-sized fiber optode having ratiometric calibration was examined and successfully explained by response theory. Our method gives a general preparation for ultrasmall ion-selective fiber optodes because other ion-selective optodes can be obtained simply by replacing the tailed ionophore.

One simple example of a rapid flow-through analysis (RFA) system based on ion-selective optode detection was demonstrated, and its performance was discussed. The RFA is a flow analytical method based on a reagentless analyte flow injection system combined with an analyte selective monitor/sensor such as an optical chemical sensor (optode) involving mathematical response simulation using a semi-empirical theoretical response equation. The response of RFA with optode detection can basically be expressed by the equation derived from Fick's law of diffusion and Kubelka-Munk's law, and two other variable parameters in relation to the experimental response. Mathematically simulated results using the proposed equation indicated that the equation can be useful for the prediction of the flow analytical response. In the present demonstration of RFA, highly selective ionophores based on 16-crown-5 derivatives were used for the ion-sensing component of the optode for sodium ion determination. A sodium ion-selective optode based on C14-DD16C5 and KD-A3 exhibited high selectivity for sodium ion over potassium ion, with a selectivity coefficient (logK(i,j)(opt)) of -2.6. This optode responded to sodium ion in the concentration range from 10-5 to 10-1M at pH 8.0 by measuring the absorbance change at 510nm in the sensing phase of the optode. The RFA system equipped with a sodium ion-selective optode offers a reagent-less advanced ion-determination methodology for conventional flow injection analysis.

The sensing membrane is a plasticized poly(vinyl chloride)-based copolymer with a neutral sodium ionophore and an anionic dye. To fabricate a micrometer-sized fiber optode, a 'micropipet fabrication method' was proposed to fix a liquid membrane-based optode on the small tip of an optical fiber probe, in which the optode size can be varied from ~1 μm to more than 10 μm. Our first optode incorporated a 16-crown-5 derivative as the neutral sodium ionophore and a dibromofluorescein derivative as the single-emission anionic dye. The sensor response was monitored by measuring the fluorescence intensity under a time-resolved photon-counting method. At the first stage of the investigation, it was found that the ionophore including a sodium ion in its cavity leached from the membrane phase. However, we have discovered that the problem can be resolved by using a 'tailed' ionophore, which is an ionophore possessing a lipophilic long alkyl chain. The 'tail' of the ionophore functions as an 'anchor' that prevents leaching of the ionophore from the membrane phase into the water phase. The anchor effect of the tailed ionophore was clearly demonstrated with 6-μm-sized sodium ion-selective optodes. Using a 3-μm-sized optode, the sensor response was examined and successfully explained by the response theory. The size limitation of the optode was also examined using the response features of a 1.5-μm-sized fiber optode. The second optode incorporated a tailed 16-crown-5 derivative as the neutral sodium ionophore and a coumarin derivative as the dual-emission anionic dye. The second optode is more practical than the first optode because the problem of fluorescence distortion due to photobleaching and solvent effect is resolved by ratiometric calibration where the sensor response is monitored by the spectral shift of the dual-emission fluorescence. The sensor response of an 8-μm-sized fiber optode having ratiometric calibration was examined and successfully explained by the response theory.

The chemistry of the ion-selective optode has recently been recognized as a highly selective ion-sensing methodology which involves a highly selective complexation between an ionophore and a primary ion. This simple methodology allowed the construction of several kinds of ion-sensing devices which enabled highly selective ion determination for analytical purposes. In this review, sensing devices are divided into the following four types with different analytical uses: (1) flow analytical devices (flow-through optode); (2) waveguide devices (waveguide optode); (3) sensing plate devices (sensing plate optode, film optode); (4) fiber-optic devices (fiber optode). The characteristics of each device are explained and discussed with experimental data, and the future prospects for ion-selective optode methodology are described.

By utilizing "multiinformation dyes (MIDs)", which have plural spectral change characteristics such as an absorption maximum wavelength (λmax) shift based on a polarity change and an absorbance change due to protonation, novel λmax-tunable ion-selective optodes were proposed and prepared by employing MIDs with membrane solvents having different polarities. For controlling the detecting λmax of the optode, the novel polar membrane solvent [2-[[6-(2-nita)phenoxy)hexyl]oxy]methyl]isobutane-1,3-diol was designed and synthesized, which was used together with a typical membrane solvent nitrophenyl octyl ether. By mixing these two membrane solvents, the λmax position of the optode detection wavelength can be shifted and controlled and was successfully applied to a λmax-tunable Li+-selective optode based on a highly Li+-selective ionophore TTD14C4. The λmax tuning technique is useful for preparing an optode system using a low-cost light source such as a light-emitting diode or a popular laser. © 1998 American Chemical Society.

The molecular design of multi-functional dyes, called 'multi-information dyes' (MIDs), and their application to several methods of optical chemical sensing were proposed. The concepts for the molecular design of the dyes were as follows: (1) the introduction of multiple (both positive and negative) charges on both ends of the large conjugated π-electron system of the dye molecule, so that the dye interacts with many chemical species or environments; (2) the introduction of different substitution (electron-donating or electron-accepting) groups in the conjugated π-electron system of the dye molecule, so that the dye has a different pK(a) and solvatochromic property; and (3) the introduction of an immobilization site in the dye molecule, so that the dye can be easily prepared as a sensing probe.Based on these concepts, sixteen kinds of dyes were synthesized, all being of the merocyanine type. The basic color-change characteristics of the MIDs were evaluated with a homogeneous system and a solvent extraction two-phase system. Some of these dyes (e.g., KD-M5) offered two-dimensional sensing information for sensing the water content in organic solvents, in which the absorbance maximum wavelength (λ(max)) shift and absorbance change were both utilized as the detecting signals.From these results, the MIDs developed in this study have several possibilities for analytical applications in optical chemical sensing such as pH sensing, ion sensing, neutral molecule sensing, and water content-sensing in organic solvents.

In this paper, an active PVC optical thin-film waveguide sensor is proposed which can select a specific ion and measure its concentration. The waveguide was fabricated using the plasticized poly(vinyl chloride) (PVC), bis ethyl hexyl phthalate (BEHP), lipophilic anionic dye (LAD-3), and ionophores (K23E1 for calcium, or C14DD16C5 for sodium) in which the PVC membrane plays important roles for both incident light propagation and selective ion sensing. In order to investigate the applicability of this sensor to Ca2+ and Na+ measurement, the sensor was applied to sample solutions whose CaCl2 concentration was gradually altered. Also, we applied it to a NaCl solution. In this experiment, we found that this PVC thin-film waveguide possessed good light propagation for argon laser light at 488 nm. Also, the comparison of the experimental responses between the active waveguide sensor and a commonly utilized waveguide sensor (evanescent waveguide spectrometry), indicated that the sensitivity of the active waveguide sensor is obviously higher than that of the conventional waveguide sensor. These findings suggested that the proposed PVC waveguide ion sensor is applicable to the determination of various ions with high sensitivity.

Rapid flow-through analysis (RFA) based on optode (optical chemical sensor) detection is proposed, and its performance is discussed using the RFA system equipped with a pH-sensitive optode as a model case. To demonstrate and understand the usefulness of the RFA system, long-lifetime pH-sensitive optodes were prepared using a hydrophilic poly(hydroxyethyl methacrylate) (poly-HEMA) membrane covalently immobilized with a dye containing an amino group such as Congo Red or Nile Blue. The response equation for the optode with the RFA system was proposed, and satisfactory estimation for rapid pH analysis was obtained. The proposed RFA can stand as an advanced method for conventional flow injection analysis.

Highly selective ion sensing film optodes for the determination of four kinds of ions (Na+, K+, Ca2+, Cl-) were prepared with plasticized PVC membranes containing the respective ionophores and a newly prepared lipophilic anionic dye. The principle of the optical response of these sensing films is based on ion-pair extraction of the ion-ionophore complex and a deprotonated or protonated lipophilic anionic dye. These film optodes are for disposable use and can detect ions by simply immersing them into a glass vessel which is filled with the samples solution and determining the ion by measuring the absorbance change at the respective maximum absorption wavelength of the lipophilic anionic dyes in the visible region. The theoretical response of these films was also discussed based on the ion-extraction model. The ion selectivity of these films was sufficient for the determination of Na+, K+, Ca2+ and Cl- in diluted serum samples, and satisfactory results were obtained in serum analysis. © 1995.

© 17CBMS-0001. In this study, novel concept of micrometer-scale spectrometer (P-spectrometer) composed of imprinted photonic crystal nanocavities (PCNs) was proposed. The P-spectrometer has sufficient size to integrate into microfluidic devices and possible to detect light absorption high sensitively. Here we fabricated a PCN as unit cell of P-spectrometer using nanoimprint lithography, and experimentally confirmed for the first time that the fabricated PCN worked as a detection module for 560 nm wavelength.

© 17CBMS-0001. This paper reports the preparation of the polyethylene glycol-coated graphene oxide (PEG-GO) possessing highly dispersive, fluorescence quenching and size separation functions, and its application to “single-step” immunoassay. The present immunoassay microdevice was fabricated by combining PDMS microchannel arrays separately immobilizing PEG-GO and fluorescently-labelled antibody as soluble coatings. When a sample solution was introduced into the microdevice by capillary action, all the reagents spontaneously mixed, reacted, and free fluorescently-labelled antibody was penetrated into the PEG structure and effectively quenched. Thus the antigen was successfully detected by single-step operation from the change of fluorescence intensity.

We systematically investigated the reversibility of response, sensitivity and response time, and demonstrated rapid and highly-sensitive anion sensing based on the coextraction of anions and protons into the bulk of the plasticized PVC membrane. We prepared a microchannel array device combined with plasticized PVC membrane, and Cl- sensing using flat-bed scanner was successfully demonstrated.

Developed RRC-assembled device provided a rapid, simple and multiple enzyme activity assay by only introducing a sample solution by capillary action. The enzyme reaction products were then concentrated on the basis of double sweeping using both the cationic and anionic micelles from the RRGs by applying voltage. As a result, a rapid, simple, sensitive, and simultaneous assay of caspase-3, trypsin, and alkaline phosphatase was successfully realized by the developed device.

Here, we report the newly prepared polyethylene glycol (PEG)-coated graphene nanoparticle (PGN) possessing fluorescence quenching and size separation functions, and its application to single-step immunoassay. The PGN was prepared by the coacervation method, and by optimizing the preparation condition, PGN successfully separated the free fluorescently-labelled antibody and immunocomplex by size difference. By separately adsorbing fluorescently-labelled antibody and PGN onto the inner wall of two PDMS microchannel arrays and combining, the present immunoassay microdevice was prepared. Finally, by introducing a sample solution by capillary action, we successfully measured the C-reactive protein (CRP) as a model antigen within 2 min.

© The Japan Society for Analytical Chemistry. In this study, a fast and easy-to-use capillary-type microdevice for competitive bioassay is proposed. The device is composed of polydimethylsiloxane (PDMS) microchannel arrays that separately immobilize polyethylene glycol (PEG) coating, which contained graphene oxide (GO)-analyte conjugates and fluorescently-labelled receptor proteins. The working principle of the device involved the spontaneous dissolution of the PEG coating, subsequent mixing and reaction with analyte to give fluorescence response, triggered by the capillary action-mediated introduction of a sample solution. For principle verification, a competitive biotin assay was successfully demonstrated within 20 s in a single-step operation by detecting the change in fluorescence via microscopy.

Here, we report a new principle of single-step enzyme immunoassay by using a newly-synthesized lipophilic fluorescent substrate, which can be immobilized to a plasticized polyvinyl chloride (PVC) coating by hydrophobic interaction. The plasticized PVC was coated inside a square glass capillary and further coated by hydrogel coating as a second layer which worked for discriminating antigen-antibody complex and free antibody. Then soluble coating containing enzyme-labeled antibody was coated as a third layer to successfully prepare a capillary for single-step immunoassay. Introducing a sample solution by capillary action allowed successful single-step immunoassay of cancer marker protein, alphafeto protein (AFP).

Caspase-3 inhibitor assay important in drug development was successfully integrated into "Single-Step" by solving the problem of low-activity enzyme immobilization. We developed a combinable PDMS capillary (CPC) sensor for enzyme inhibition assay using the concave- and convex-type PDMS substrates. In the conventional enzyme inhibitor assay, complicated analytical procedures, such as mixing and dissolution, are required. In contrast, this sensor allows single-step assay possible only by sample introduction via capillary action. Total reaction time was reduced from lh to 3-5 min, and simultaneous acquisition of multiple data required to determine IC50 value was successfully achieved by using CPC sensor array.

Simple and rapid immunoassay based on micro isoelectric focusing (IEF) was newly developed by using hydrogels containing acid or base as ion suppliers. The prepared hydrogels have enough mechanical strength and can eliminate a handling operation of acid and base solutions which often causes an unfavorable hydrodynamic flow in conventional IEF. As a result, the proposed device provided the easy-to-use reagent release capillary-IEF (RRC-IEF). The RRC-IEF with reagent release hydrogels was also applied to microscale immunoassay, realizing a simple and rapid immunoassay by concentration and separation of the bound/free analytes within 10 min.

A conventional flatbed scanner was employed for direct detection of colored solution in capillary-based micro analytical device. Since the flatbed scanner is a common and inexpensive detection equipment (usually ∼ 50 USD), establishing the method for detecting colored solution within capillary or microchannel would allow us widespread use of microfluidic devices including point-of-care (POC) testing. Here, scan conditions (resolution, scan direction) were systematically investigated, and determined detection limits of various colored solutions within 100 jam-sized square capillary. Finally, pH sensing was performed as a demonstration and successfully obtained a calibration curve. Copyright © (2013) by the Chemical and Biological Microsystems Society All rights reserved.

This paper reports a novel microdevice showcasing the rapid and simultaneous multi-analyte sensing of different serum components; glucose, cholesterol, pH and alkaline phosphatase (ALP). Discrimination between normal and high analyte concentration in a serum sample was achieved and results were obtained within minutes after sample introduction. The complexity of microdevice fabrication and fluid handling from our previous system, capillary-assembled microchip (CAs-CHIP) [1-2], has been circumvented in this work that led to a simple fabrication and easy operation. Furthermore, we have exploited the fluorescein-based probes for simultaneous multi-analyte sensing by using only one fluorescence filter.

In this study, we fabricated the Combinable-PDMS Capillary (CPC) sensor allowing single step assay by simply introducing a sample solution by capillary force. CPC is composed of a convex-shaped PDMS plate immobilizing undissolvable reagents and a concave-shaped PDMS plate immobilizing dissolvable reagents. Since the concave-shaped PDMS has a deeper channel size compared to that of convex structure, combining these PDMS plates allowed easy fabrication of capillary structure possessing different reagents inside the same capillary. This method is useful for immobilizing two different reagents which reacts each other. As an application, we carried out a single-step enzyme inhibitor assay using the CPC. First, a fluorescent substrate is immobilized with Polyethylene glycol (PEG) on concave-shaped PDMS plate. Secondly, trypsin, an enzyme, is quantitatively immobilized using Layer-by-Layer (LbL) technique on convex-shaped PDMS plate. Then these PDMS plates are combined to fabricate CPC for enzyme inhibitor assay. Buffer solution containing various concentrations of leupeptin, a trypsin inhibitor, is introduced into the capillary, then inhibition curve was obtained. © 2009 CBMS.

This review accounts for the current development in microfluidic immunosensing chips. The basic knowledge of immunoassay in relation to its microfluidic material substrate, fluid handling and detection mode are briefly discussed. Here, we mainly focused on the surface modification, antibody immobilization, detection, signal enhancement and multiple analyte sensing. Some of the clinically important currently implemented on the microfluidic immunoassay chips are C-reactive protein (CRP), prostate specific antigen (PSA), ferritin, vascular endothelial growth factor (VEGF), myoglobin (Myo), cardiac troponin T (cTnT), cardiac troponin I (cTnI), and creatine kinase-cardiac muscle isoform (CK-MB). The emerging microfludic immunosensor technology may be a promising prospect that can propel the improvement of clinical and medical diagnosis. © 2008 Elsevier B.V. All rights reserved.

A novel capillary immunosensor capable of single-step heterogeneous sandwich immunoassay for capillary-assembled microchip (CAs-CHIP) integration is presented. It is mainly composed of a covalently attached primary antibody and non-covalently immobilized secondary labeled antibody in the inner wall of the square glass capillary. Sample solution containing antigen enters via capillary force resulting to the release of the secondary labeled antibody and immunocomplex formation occurs on the capillary wall followed by fluorescence detection. Here, the capillary immunosensor contains the fluorescein-labeled and unlabeled anti-human IgG for non-covalent and covalent immobilization, respectively. The immunosensor respond successfully to changes in human IgG concentration. © 2008 CBMS.

© 2007 CBMS. A simple sensing conduit for capillary-assembled microchip (CAs-CHIP) integration that is capable of metabolite detection by fluorescence microscopy is developed. This sensing capillary called enzyme-release capillary (ERC) contains enzyme/s that are adsorbed inside the square glass capillary with the aid of polyethylene glycol acting as scaffold. Metabolite solution enters the conduit via capillary force and the enzyme/s are released leading to the detection of a fluorescent biochemical product. Here, the stability of the E-galactosidase immobilized capillary is observed to last for almost a month. Moreover, the co-immobilized glucose oxidase-peroxidase-thiamine system for glucose measurement showed a detection limit of about 30 PM.

A novel concept of assembling various chemical functions onto a single microfluidic device is proposed. The concept, "CAPILLARY-ASSEMBLED MICROCHIP (CAs-CHIP), involves embedding chemically functionalized square capillaries onto a lattice microchannel network fabricated on polydimethyl siloxane (PDMS) possessing same channel dimensions to outer dimensions of square capillaries (Figure 1). This approach would allow easy fabrication of chemically-functionalized microfluidic device by freely embedding functional square capillaries on PDMS microchannel network. Here we report a fabrication method of CAs-CHIP, and an application for preparing a multiple chemical sensing chip as an example.

This review focuses on chemical and biochemical analysis systems using pressure-driven microfluidic devices or microchips. Liquid microspace in a microchip has several characteristic features, for example, short diffusion distances, high specific interfacial area and small heat capacity. These characteristics are the key to controlling micro unit operations and constructing new integrated chemical systems. By combining multiphase laminar flow and the micro unit operations, such as mixing, reaction, extraction and separation, continuous flow chemical processing systems are realized in the microchip format. By applying these concepts, several different analysis systems were successfully integrated on a microchip. In this paper, we introduce the microchip-based chemical systems for wet analysis of cobalt ion, multi-ion sensors, immunoassay, and cellular analysis. © 2002 Elsevier Science B.V.

This review focuses on the integration of chemical and biochemical analysis systems into glass microchips for general use. By combining multiphase laminar flow driven by pressure and micro unit operations, such as mixing, reaction, extraction and separation, continuous-flow chemical processing systems can be realized in the microchip format, while the application of electrophoresis-based chip technology is limited. The performances of several analysis systems were greatly improved by microchip integration because of some characteristics of microspace, i.e., a large specific interface area, a short molecular diffusion time, a small heat capacity and so on. By applying these concepts, several different analysis systems, i.e., wet analysis of cobalt ion, multi-ion sensor, immunoassay, and cellular analysis, were successfully integrated on a microchip. These microchip technologies are promising for meeting the future demands of high-throughput chemical processing.

In this paper, a PVC optical thin-film waveguide sensor is proposed which can select a specific ion and measure its concentration depending on materials added into waveguide membrane. In order to investigate the applicability of this sensor to Ca++ and Na+ measurement, the waveguide was fabricated with poly vinyl chloride (PVC), bis ethyl hexyl phthalate (BEHP), lipophilic anionic dye (LAD-3), and ionophores (K23E1 for Ca++ or C14DD16C5 for Na+). For this purpose, we applied the sensor to sample solution whose CaCl2 concentration was gradually altered. Also, we applied it to NaCl solution. In this experiment, we found that this PVC thin film waveguide possessed good ray propagation at 488 nm of argon laser. In addition, it showed the chemical reaction to ion enough to select it and measure its concentration. These findings suggested that the proposed PVC waveguide ion sensor is applicable to various ions.
