Abstract
An apparatus includes a biosensor integrated circuit (IC) chip having multiple well structures configured to receive a liquid comprising one or more biological analytes. The well structures include a passivation layer with an opening over one or more field effect transistors (gFETs) which include a layer of 2D channel material selected from molybdenum disulfide (MoS2) and graphene; a drain electrode connected to a first end of the channel; a source electrode connected to a second end of the channel, wherein the individual gFETs are configured such that liquid received by the well structure is confined to form a liquid gate above a top surface of the channel. A system and method perform various functions of the apparatus.
