The identification of secreted proteins in cell culture supernatants is a useful method for the noninvasive evaluation of cultured cells. Herein, we show that a fingerprint-based sensor techniqu ... Read More

Here, we present a novel imaging system that enables multiple reductants to be detected simultaneously in real time. Previously, we developed a novel electrochemical imaging system using an LSI- ... Read More

Positioning and patterning of polystyrene particles on a silicon nitride (SiN) membrane with a microhole array has been demonstrated by positive dielectrophoresis (p-DEP). A chamber with an SiN ... Read More

The surface modification of the polydimethylsiloxane (PDMS) elastomer was studied to obtain a durable hydrophilic surface leading to the reduction in surface tension with an aqueous solution for ... Read More

We present a novel chemical sensor based on electroosmotic flow (EOF) for the simple detection of chemical adsorption in an aqueous solution. Fundamental investigations for the optimization of a ... Read More

The sensitivity of a waveguide-mode sensor, which has a sensing plate incorporating a thin single-crystalline Si layer and a thin SiO2 glass layer on a silica glass substrate, can be improved by ... Read More

In this research, we apply the near field excited by waveguide mode (WGM) to the illumination of a total internal reflection fluorescence (TIRF) microscope. By utilizing the electric field enhan ... Read More

Bioluminescence resonance energy transfer (BRET) is a useful technique for visualizing cellular functions and responses to stimuli. To construct efficient biosensing protein probes using BRET, n ... Read More

In this study, we provide a cross-sectional comparison of existing influenza virus detection methods in terms of their sensitivity, sample volume required, and process time needed for an assay. ... Read More

The standard method of detaching adherent cells from a culture substrate involves the application of trypsin to digest the extracellular matrix. However, the trypsin treatment is time-consuming ... Read More

Herein, we report on the development of an organic FET (OFET)-based pH sensor. To accomplish the electrical sensing of pH, the designed OFET has an extended-gate electrode consisting of a surfac ... Read More

Dermatitis (skin inflammation) is becoming a serious health problem that lowers the quality of life. Microfluidic devices have been employed as an alternative to conventional in vitro skin model ... Read More
