  • Point-of-care apparatus and methods for detecting cancer using electrochemical impedance or capacitance spectroscopy
    Patent number: 11740202
    Abstract: The presence of biomarkers or other analytes can be detected in the bodily fluid using Electrochemical Impedance Spectroscopy (EIS) or Electrochemical Capacitance Spectroscopy (ECS) in devices, such as handheld point-of-care devices. The devices, as well as systems and methods, utilize using Electrochemical Impedance Spectroscopy (EIS) or Electrochemical Capacitance Spectroscopy (EIS) in combination with an antibody or other target-capturing molecule on a working electrode. Imaginary impedance or phase shift, as well as background subtraction, also may be utilized.
    Type: Grant
    Filed: August 31, 2018
    Date of Patent: August 29, 2023
    Assignee: ADVANCED TEAR DIAGNOSTICS, LLC.
    Inventors: Andrew Douglas Penman, Marcus Willard Smith, Catalina Valencia, Sergei A Svarovsky
