Risa Kohiyama is a prominent inventor based in Gosen, Japan. She has made significant contributions to the field of immunochromatography, holding a total of 5 patents. Her innovative work focuses on enhancing the sensitivity and accuracy of detection methods in various applications.

Latest Patents

Kohiyama's latest patents include a method of amplifying detection light using light-reflecting material in immunochromatography. This invention aims to provide an immunochromatographic test piece that achieves both highly sensitive detection of a target substance and a simple test piece structure, which are typically challenging to reconcile. The test piece comprises a membrane with a capture substance immobilized on it, allowing for the accumulation of insoluble carrier particles that bond to the target substance. The membrane is then irradiated with light to detect emitted light from the accumulated particles, while a light-reflecting material is positioned on the opposite side of the membrane to enhance detection capabilities.

Another notable patent is the immunochromatographic device designed to reduce background noise. This invention improves visibility by minimizing background interference, enabling accurate detection of signals from target substances. The device features a membrane with a detection region where an antibody or antigen is immobilized, facilitating the capture of target substances. A colorant complementary to the labeling carrier's color is included in a dry state within the device, allowing for effective specimen development.
