Abstract
ABSTRACTNovel 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.
