Abstract
Embodiments herein include a kinetic response system for measuring analyte presence on a chemical sensor element. The chemical sensor element includes one or more discrete binding detectors, each discrete binding detector including a graphene varactor. The kinetic response system includes a measurement circuit having an excitation voltage generator for generating a series of excitation cycles over a time period. Each excitation cycle includes delivering a DC bias voltage to the discrete binding detectors at multiple discrete DC bias voltages across a range of DC bias voltages. The kinetic response system includes a capacitance sensor to measure capacitance of the discrete binding detectors resulting from the excitation cycles. The kinetic response system includes a controller circuit to determine the kinetics of change in at least one of a measured capacitance value and a calculated value based on the measured capacitance over the time period. Other embodiments are also included herein.
