Abstract
An improved sensing method is provided for rapid analyte detection. The method includes: applying an AC excitation signal to the channel region of the transistor; applying an AC drive signal to the transistor; delivering an analyte of interest to a channel region of a transistor; and monitoring a mixing current of the excitation signal and the drive signal through the transistor, where a change in the mixing current is indicative of the concentration of the analyte of interest.
