Abstract
Novel strategies of transduction may help to improve the biosensor performance by enhancing its sensitivity or linearity or by allowing a better integration with the electronics, which in turn favors the miniaturization of the sensing devices. In this work, a combination of a conductometric element containing the bioreceptor with a MOSFET is proposed as a transduction strategy. Simulations of the gate voltage and drain current versus conductance curves are used to confirm the feasibility of the proposed strategy. One of the advantages of the presented device is that the sensing element can be deposited by back-end processes compatible with current IC technology.
