Abstract
A bioFET cell for measuring a time dependent characteristic of an analyte bearing fluid includes a source, a drain, a semiconductive single wall carbon nanotube network layer extending between the source and drain electrodes and electrically coupled there between, a gate insulatively spaced from and disposed over and extending between the source and drain electrodes, a layer of at least one selected antibody disposed on and linked to the polymer layer to functionalize the semiconductive single wall carbon nanotube network layer to a selected target biomarker corresponding to the at least one selected antibody so that electron transport into the semiconductive single wall carbon nanotube network layer is facilitated, where the source, drain and gate electrodes with the carbon nanotube network layer form a defined channel through which the analyte bearing fluid may flow, and a high impedance source follower amplifier coupled to the source electrode.
