Yukichi HORIGUCHI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Device for biological material detection, detection apparatus for biological material detection, method for measuring ion current, and method for identifying biological material
    Patent number: 10877021
    Abstract: A device for biological material detection includes a substrate; a through-hole through which a biological material to be tested passes, the through-hole being formed in the substrate; a molecule that interacts with the biological material to be tested passing through, the molecule being formed in the through-hole; a first chamber member that forms, with at least the surface including the through-hole on one surface side of the substrate, a first chamber to be filled with electrolyte; and a second chamber member that forms, with at least the surface including the through-hole on the other surface side of the substrate, a second chamber to be filled with electrolyte. The biological material to be tested is identified by the waveform of the ion current (passage time, shape, etc.) when the biological material to be tested passes through the through-hole.

  • MODIFIED NANOPARTICLE, DISPERSION CONTAINING MODIFIED NANOPARTICLE, SET FOR RESISTIVE PULSE SENSING, SET AND REAGENT FOR DETECTING VIRUS OR BACTERIUM, AND METHOD FOR DETECTING VIRUS OR BACTERIUM
    Publication number: 20200166506
    Abstract: A modified nanoparticle includes a nanoparticle, a dispersibility improving group bound to a surface of the nanoparticle, and an oligosaccharide that is bound to the surface of the nanoparticle, and that selectively captures a specific virus or bacterium. A reagent for detection of a specific virus or bacterium by resistive pulse sensing is also provided, the reagent including the modified nanoparticle.
