WebLimit of Detection of Silicon BioFETs Nitin K. Rajan Yale University 2013 Over the past decade, silicon nanowire/nanoribbon eld-e ect transistors (NWFETs) have demonstrated great sensitivity to the detection of biomolecular species, with limits of detection (LOD) down to femtomolar concentrations. Several well known factors limit the LOD; among ... A field-effect transistor-based biosensor, also known as a biosensor field-effect transistor (Bio-FET or BioFET), field-effect biosensor (FEB), or biosensor MOSFET, is a field-effect transistor (based on the MOSFET structure) that is gated by changes in the surface potential induced by the binding of molecules. … See more Bio-FETs couple a transistor device with a bio-sensitive layer that can specifically detect bio-molecules such as nucleic acids and proteins. A Bio-FET system consists of a semiconducting field-effect transistor that acts as a See more The principle of operation of Bio-FET devices based on detecting changes in electrostatic potential due to binding of analyte. This the … See more The MOSFET (metal–oxide–semiconductor field-effect transistor, or MOS transistor) was invented by Mohamed M. Atalla and Dawon Kahng in 1959, and demonstrated in 1960. Two years later, Leland C. Clark and Champ Lyons invented the first biosensor in … See more The fabrication of Bio-FET system consists of several steps as follows: 1. Finding a substrate suitable for serving as a FET site, and forming a FET on the substrate, 2. Exposing an active site of the FET from the substrate, See more The choice of reference electrode (liquid gate) or back-gate voltage determines the carrier concentration within the field effect transistor, and therefore its region of operation, therefore the response of the device can be optimised by tuning the gate voltage.
