Abstract
The disclosure describes methods, devices, and system that measure chemisorption potentiometrically for detection of target molecules. In one example, a device includes a semiconductor, an ionic conducting electronic insulator coupled to the semiconductor, a floating gate electrode comprising a first portion and a second portion, the first portion being coupled to the semiconductor via the ionic conducting electronic insulator, an aqueous buffer, and a primary gate electrode coupled to the second portion of the floating gate electrode via the aqueous buffer. The second portion of the floating gate electrode may comprise a probe configured to react with a target chemical composition of a molecule to detect the presence of the molecule. Reaction with the target chemical composition may change an electrical property of the device and indicate the presence of the molecule in the aqueous buffer.
