Aptamer-Enhanced Organic Electrolyte-Gated FET Biosensor for High-Specificity Detection of Cortisol

Organic field-effect transistor (FET) devices offer a low-cost manufacturing and simple integration of biorecognition molecules for biosensory applications. In electrolyte-gated organic FET (EGOFET) biosensors, a biofluid is directly integrated as the OFET gate dielectric for label-free bioelectronic sensing. The critical constraints of these devices are biofouling and the organic polymer's suscep...
