POINT-OF-CARE APPARATUS AND METHODS FOR DETECTING CANCER USING ELECTROCHEMICAL IMPEDANCE OR CAPACITANCE SPECTROSCOPY

摘要

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.
