Abstract
In this study, we report an inkjet printing-based method for the immobilization of different reactive analytical reagents on a single microchannel for a single-step and homogeneous solution-based competitive immunoassay. The immunoassay microdevice is composed of a poly(dimethylsiloxane) microchannel that is patterned using inkjet printing by two types of reactive reagents as dissolvable spots, namely, antibody-immobilized graphene oxide and a fluorescently labeled antigen. Since nanoliter-sized droplets of the reagents could be accurately and position-selectively spotted on the microchannel, different reactive reagents were simultaneously immobilized onto the same microchannel, which was difficult to achieve in previously reported capillary-based single-step bioassay devices. In the present study, the positions of the reagent spots and amount of reagent matrix were investigated to demonstrate the stable and reproducible immobilization and a uniform dissolution. Finally, a preliminary application to a single-step immunoassay of C-reactive protein was demonstrated as a proof of concept.

Abstract
In this study, a simple and highly sensitive enzyme activity assay based on reagent-release capillary-isoelectric focusing is described. Reagent-release capillaries containing a fluorescent substrate, which produces fluorescent products possessing an isoelectric point after reaction with enzymes, provides a simple procedure. This is because it allows to spontaneously inject a sample solution into the capillary by capillary action, mixing reagents, and subsequently concentrating the fluorescent products based on isoelectric focusing. Fluorescent rhodamine 110 and its monoamide derivative, which were generated as a final product and an intermediate, respectively, were then focused and separated by reagent-release capillary-isoelectric focusing. After 30 min of enzyme reactions, two focused fluorescent bands were clearly isolated along the prepared capillaries. Employing the focused band of rhodamine 110 monoamide allowed for highly sensitive detection of enzyme activity in the 10 pg mL(-1) order, while that of the conventional assay using a microplate was in the ng mL(-1) order. Furthermore, arraying reagent-release capillaries of different substrates on a chip allowed for simultaneous multi-assay of enzyme activity with good sensitivity in the pg mL(-1) order for each protein.

Abstract
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.

Abstract
We describe a new method for fabricating a capillary-type sensor, called a combinable poly(dimethyl siloxane) (PDMS) capillary (CPC) sensor. The method for preparing the CPC simplifies enzyme inhibitor assays into a simple, single step assay. The sample inhibitor solution is introduced by capillary action. This triggers the spontaneous dissolution of physically adsorbed fluorescent substrates, and the substrate mixes with the inhibitor. This is followed by competitive reaction with insoluble enzyme to give a fluorescence response. CPC is composed of a convex-shaped PDMS stick containing reagents immobilized in an insoluble coating, and a concave-shaped PDMS stick containing reagents immobilized in a soluble coating. Since the concave-shaped PDMS has a deeper channel than the convex structure, combining these PDMS sticks is like closing the zipper of a "freezer bag". This allows easy fabrication of "thin and long" capillary structures containing different reagents inside the same capillary, without the need for precise alignment. This method allows the immobilization of two reactive reagents, such as enzyme and substrate required for a single step assay, which are typically very difficult to immobilize using commercially available conventional capillaries. Furthermore, by simply arraying various CPCs, the CPC sensor allows multiple assays. Here, we carried out a single-step enzyme inhibitor assay using the CPC. In addition, two independent CPCs were arrayed to demonstrate multiple assaying of a protease inhibitor.

Abstract
This report describes the fabrication and characterization of a simple and disposable capillary isoelectric focusing (cIEF) device containing a reagent-release capillary (RRC) array and poly(dimethylsiloxane) (PDMS) platform, which allows rapid (within 10 min) screening of cIEF conditions by introducing a sample solution into plural RRCs by capillary action followed by electric field application. To prepare the RRC, covalent immobilization of poly(dimethylacrylamide) (PDMA) was conducted to suppress electro-osmotic flow (EOF), followed by physical adsorption of the mixture of carrier ampholyte (CA), surfactant, labeling reagent (LR), and other additives to the PDMA surface to construct a two-layer structure inside a square glass capillary. When the sample solution containing proteins was introduced into the RRC, physically adsorbed CA, surfactant, and LR can be dissolved and released into the sample solution. Then, complexation of LR with proteins, mixing with CA and surfactant, and exposure of the PDMA surface spontaneously occurs for the IEF experiments. Here, three different RRCs that immobilize different CAs were prepared, and simultaneous cIEF experiments involving hemoglobin AFSC mixtures for choosing the best CA demonstrated the proof of concept.

Abstract
Inductively coupled plasma-mass spectrometry (ICP-MS)-based assays lend themselves to multiplexing due to the high resolution between mass channels, the sensitivity, and the reliability of the technique. Here the potential of ICP-MS-based protease assays is demonstrated with a quadruplex assay of cysteine proteases and metalloproteases. Four orthogonal peptide substrates were synthesized for the proteases calpain-1, caspase-3, matrix metalloprotease-9 (MMP-9), and a disintegrin and metalloprotease-10 (ADAM10). Each substrate carries a biotin tag at the C terminus and a diethylenetriaminepentaacetic acid (DTPA)-based lanthanide complex at the N terminus. The results demonstrate that this is a simple and reproducible analysis technique with excellent correlation between the single and multiplex assay formats.

Abstract
Rapid, sensitive, and quantitative assays for proteases are important for drug development and in the diagnosis of disease. Here an assay for protease activity that uses inductively coupled plasma-mass spectrometry (ICP-MS) detection is described. Peptidic alpha-chymotrypsin substrates were synthesized containing a lanthanide ion chelate at the N terminus to provide a distinct elemental tag. A biotin label was appended to the C terminus of the peptide, allowing separation of uncleaved peptide from the enzymatic digestion. The enzyme activity was determined by quantifying the lanthanide ion signal of the peptide cleavage products by ICP-MS. Biotinylated substrates synthesized include Lu-DTPA-Asp-Leu-Leu-Val-Tyr approximately Asp-Lys(biotin) and Lu-DTPA-betaAla-betaAla-betaAla-betaAla-Gly-Ser-Ala-Tyr approximately Gly-Lys-Arg-Lys(biotin)-amide. Parallel assays with a commercially available fluorogenic substrate (Suc-AAPF-AMC) for alpha-chymotrypsin were performed for comparison. Using the ICP-MS assay, enzyme concentrations as low as 2pM could be readily detected, superior to the detection limit of an assay using the alpha-chymotrypsin fluorogenic substrate (Suc-AAPF-AMC). Furthermore, we demonstrated the use of this approach to detect chymotrypsin activity in HeLa cell lysates.
