Supporting the Health of Mind and Body with Molecular Chemistry and Semiconductor Technology

KOKOROMI Inc. is developing biosensor technology that immobilizes proteins and nucleic acid--as aims to provide a technology that can repeatedly measure the concentration of specific biomolecules using a biosensor in which proteins or nucleic acids—capable of capturing specific biomolecules—as uniform molecular films on semiconductor chips. These sensors are designed for repeated measurements with high precision and reproducibility.

 

For example, biosensors that measure molecules that indicate immune function using saliva or sweat enable easy health checks at home or in the workplace. The photo above shows a demonstration of a prototype adhesive sensor that measures ion concentration in sweat using nanosheets.

 

They can also be applied to understanding stress and health conditions in pets and livestock, such as cattle. The company is also engaged in research and development of simple testing technologies for various biomarkers that can be utilized in the medical and health fields, such as viruses, food allergens, and anticancer drug concentrations in the blood.
