  • ELECTRODE AND ELECTROCHEMICAL MEASUREMENT SYSTEM
    Publication number: 20220214299
    Abstract: A carbon electrode includes a substrate, and a conductive carbon layer disposed at an upper side of the substrate and having an sp2 bond and an sp3 bond. On an upper surface of the conductive carbon layer, the concentration ratio of oxygen to carbon is 0.07 or more. The ratio of a number of sp3 bonded carbon atoms to the sum of a number of sp2 bonded carbon atoms and the number of sp3 bonded carbon atoms is 0.35 or more.
    Type: Application

  • MICROSTRUCTURE, METHOD FOR MANUFACTURING SAME, AND MOLECULE DETECTION METHOD USING SAME
    Publication number: 20220026424
    Abstract: In order to provide a specific solution for producing a microstructure equipped with a mechanism for selectively detecting a marker molecule expressed by a target cell, or a specific biomolecule, and for detecting and identifying a molecule to be detected using the microstructure, the present invention provides a nearly hemispherical shell-shaped structure made of a first conductive material, and an electrode layer made of a second conductive material disposed on the concave side of the nearly hemispherical shell-shaped structure, wherein the first conductive material includes a magnetic material and the second conductive material includes an electrode material, and the size (diameter) of the cavity surrounded by the electrode layer on the concave side of the nearly hemispherical shell-shaped structure is in the range of about 10 nm to about 50 ?m.

  • Electrophoresis member, production thereof and capillary electrophoresis apparatus
    Patent number: 7736482
    Abstract: An electrophoresis member is produced by laying a plurality of capillaries on an adhesive layer born on a support layer to form a capillary layer, laminating thereon a second support layer, and partially removing the first support layer, the first adhesive layer and the second support layer to partially expose the capillaries to form a window portion for irradiation and detection and a sample injection portion for injecting a sample.
    Type: Grant
    Filed: February 12, 2007
    Date of Patent: June 15, 2010
    Assignees: Hitachi, Ltd., Hitachi Chemical Company, Ltd.
