Carbon Nanotube Biofet With A Local Amplifier In A System Array For Analysis Of Biomarkers And Method Of Analysis Of Same
Patent Number: US 9,810,661 B2
Date Filed: February 18, 2015
Country Filed In: USA
Product Application: bioFET Biosensor
Description:
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 therebetween, a gate insulative spaced from and disposed of 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.
Field of Use: The bioFET cell is part of Josh Shachar's exploration into developing next-generation biosensors that are capable of detecting specific biomarkers within a sample at clinically relevant levels in a simple portable point-of-care-device that can provide physicians and health-care workers rapid and affordable pathogen detection without the need for a dedicated lab and specialized technicians and all the associated cost therein.
