Abstract
A system and apparatus for direct or indirect target substance signal measurement include an integrated circuit with an array of 2D FETs with corresponding 2D transistor channels and a gate area for receiving a volume of liquid with one or more chemical or biological target substances, a conductive source electrically coupled to a first end of the 2D transistor channel, a conductive drain electrically coupled to a second end of the 2D transistor channel, a ceramic coating over the conductive source and the conductive drain and a thin film layer of synthetic biopolymer specific binding agents is adsorbed to the top surface of the 2D transistor channel. Methods for the system and apparatus and for selecting the synthetic biopolymer specific binding agents based on absorptivity are disclosed.
