Before revision: Sensing using semiconductor nanowires In an analogous way to FET devices in which the modulation of conductance (flow of electrons/holes) in the device, is controlled by electrostatic potential variation (gate-electrode) of the charge density in the conduction channel, the methodology of a Bio/Chem-FET is based on the detection of the local change in charge density, or so-called “field effect”, that characterizes the recognition event between a target molecule and the surface receptor.
