We designed and synthesized a polyethylene film that immobilizes antibodies via desthiobiotin– avidin interaction by grafting poly(acrylic acid) (PAAc) and biotin to its surface. The desthiobio ... Read More

In this work, we assessed the ability of a fiber-optic biochemical gas sensor (bio-sniffer) to directly and nondestructively measure gaseous formaldehyde (FA) released from food. In the biosniffe ... Read More

We have developed a solid-type pH sensor for dairy wagyu-rumen measurements. The pH sensor is composed of a sensing electrode of indium tin oxide (ITO) film and a metal–oxide– semiconductor f ... Read More

The brain–machine interface (BMI) or direct neural interface (DNI) has been intensively investigated for patients with physical function disorders. These interfaces are direct communication pat ... Read More

An optical biosniffer for dimethyl sulfide (DMS; seaweed-odor substance) was constructed by immobilizing flavin-containing monooxygenase type 3 (FMO3) onto the tip of a fiber optic oxygen sensor ... Read More

High-performance electrodes intended for retinal prosthesis were fabricated and evaluated. Iridium oxide (IrOx) was introduced as a high-performance material. A three-dimensional (3D) structure w ... Read More

Fluorescence imaging is a powerful tool for studying the functions of nitric oxide (NO). To improve this method of studying the mechanisms of NO related with behaviors in freely moving animals, w ... Read More

We have studied the construction of an electrochemical immunochromatography platform as one of the point-of-care testing devices from both experimental and theoretical aspects. In the electrochem ... Read More

We developed a microoptical displacement sensor on which a thermal sensor was integrated. The sensor was 3 × 3 mm2 in size and 0.7 mm thick including the optical power source and thermal sensor. ... Read More
