Title: Hiroyuki Ito: Innovator in Light Deflection and Virus Purification Technologies
Introduction
Hiroyuki Ito is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the fields of optical technology and virology, holding a total of 11 patents. His innovative work focuses on improving light deflection devices and developing methods for purifying virus-like particles.
Latest Patents
One of Hiroyuki Ito's latest patents is a light deflection device designed to enhance the radiation efficiency of radiated light beams. This device utilizes a photonic crystal waveguide with a lattice array of low refractive index parts, which are periodically arranged on a high refractive-index member. The dual-periodic structure of the lattice array consists of two distinct periodic arrays, each differing in the arrangement of the low refractive index parts. A line defect, where no low refractive index parts are present, serves as a waveguide core for propagating incident light. Notably, the cross-section of at least one of the periodic arrays is asymmetrical in the thickness direction of the low refractive index parts.
Another significant patent involves a purification method for norovirus virus-like particles (VLPs). This innovative method establishes a novel means for purifying VLPs by contacting a solution containing norovirus VLPs with a hydroxyapatite chromatography support. The virus-like particles bind to the support, which is then washed with a buffer before eluting the particles with a phosphate-containing buffer, where the phosphate concentration is less than 10 mM.
