  • Nanogrid electrochemical sensor for detection of biochemical species by electrochemical impedance spectroscopy
    Patent number: 10527577
    Abstract: Improved electrochemical impedance spectroscopy assays are provided by electrodepositing metallic nanoparticles onto the working electrode for electrochemical impedance spectroscopy. The metallic nanoparticles provide improved assay sensitivity. Electrodeposition of the metallic nanoparticles firmly affixes them to the working electrode, thereby making it easier to clean the working electrode from one assay to the next assay without undesirably removing the metallic nanoparticles.
    Type: Grant
    Filed: July 18, 2017
    Date of Patent: January 7, 2020
    Assignees: The Board of Trustees of the Leland Stanford Junior University, The United States of America as represented by the Department of Veteran Affairs (Washington DC)
