Title: Innovations of Hiroyuki Takei
Introduction
Hiroyuki Takei is a notable inventor based in Hatoyama, Japan. He has made significant contributions to the field of biomolecular detection and measurement, holding a total of seven patents. His work focuses on advanced methods for detecting changes in biomolecular interactions, which have important applications in various scientific fields.
Latest Patents
One of his latest patents is an enzymatic assay for localized surface plasmon resonance (LSPR). This invention provides a method for detecting changes in the refractive index at the surface of an LSPR detection system. The method involves generating an insoluble product from an enzymatic substrate using an immobilized enzyme, which accumulates at the LSPR supporting surface. Changes in the reflected or transmitted light of the surface, arising from the presence of the insoluble product, are then detected using LSPR.
Another significant patent is a measuring apparatus for biomolecule interaction. In this apparatus, a fine particle sensor surface is immersed in a buffer solution within a reaction vessel to conduct spectral measurements via optical fibers. The buffer solution is cycled through the reaction vessel, allowing for the injection of specimens and the measurement of bonding between ligands and analytes. The dissociation process of biomolecules is also measured as the concentration decreases.
