Abstract
A method for sensing biomolecules in an electrolyte includes exposing a gate dielectric surface of a sensor comprising a silicon fin to the electrolyte, wherein the gate dielectric surface comprises a dielectric material and antibodies configured to bind with the biomolecules; applying a gate voltage to an electrode immersed in the electrolyte; and measuring a change in a drain current flowing in the silicon fin; and determining an amount of the biomolecules that are present in the electrolyte based on the change in the drain current.
