Abstract
Apparatuses, systems, and methods are disclosed for chemically differentiated sensor arrays and methods of manufacturing and using the same. In one or more examples. An integrated circuit chip includes a chemically differentiated array of graphene field effect transistors with one or more wells configured to receive a volume of biological sample liquid comprising a plurality of different types of biological substances to be distinguished using electrical measurements of output signals of the graphene field effect transistors. At least one electrode is configured to apply a changing gate bias voltage (VGs) that increases and decreases within a predetermined range to the sample liquid and at least one electrode is configured to monitor measurement vectors including slopes of drain current measurements relative to the voltage measurements and differences in slope of the measurement vectors distinguish different biological substances in the sample liquid. Systems and methods utilize the integrated circuit chip.
