Engineering Biohybrid Graphene Nanoribbons for FET Biosensing with Few Molecule Sensitivity
The objective of the investigator of this project is to address two issues concerning the sensitivity of graphene Biomolecular Field Effect Transistors (Bio-FETs) in order to design more efficient tools for scientific discovery and diagnostics. Bio-FETs have shown promise in point of care diagnostics and single-molecule studies due to their direct, label-free, near real time and sensitive operation, although micro-scale Bio-FETs are insensitive compared to optical methods. Therefore, the investigator proposes to improve graphene Bio-FETs sensitivity through surface engineering of graphene to tether biomolecules and fabrication of graphene bionanostructures. Graphene nanoribbon fabrication and integration with other microfabrication techniques, in addition to selective functionalization, may also be addressed in order to enhance label-free detector sensitivity.
