  • METHOD AND APPARATUS FOR ANALYTE DETECTION USING AN ELECTROCHEMICAL BIOSENSOR
    Publication number: 20220260517
    Abstract: A method for sensing an analyte utilizing a sensor, the sensor including a reference electrode and a working electrode including an analyte-specific enzyme and a redox mediator, where the method includes: providing the working electrode to the analyte; accumulating charge derived from the analyte reacting with the analyte-specific enzyme and the redox mediator; measuring a potential drift of the working electrode relative to the reference electrode over a period of time, and correlating a rate of the potential drift to a concentration of the analyte.
