Title pH-based enzyme potentiometric sensors, Part 1, Theory
Abstract A diffusion-kinetic model for a pH based, one substrate, enzymatically coupled field effect transistor has been developed. The model includes one mobile buffer and has been solved for both transient and steady-state response. It is shown that the detection limit, slope, dynamic range, and time response are affected mainly by the buffer capacity and by the transport properties of all species involved.
