New Publication: Selective and Fast Cortisol Sensing in Human Saliva Using Graphene-based On-Chip Field-Effect Transistors
9 Oktober 2026
Our group has published a new study on an electrolyte-gated graphene field-effect transistor (EG-GFET) biosensor for the rapid and label-free detection of cortisol, a key biomarker of the human stress response. The sensor enables cortisol detection in human saliva within less than 10 minutes and operates across physiologically relevant concentrations. Importantly, measurements in real human saliva were directly benchmarked against conventional ELISA, demonstrating the potential of graphene-based biosensors for portable and point-of-care stress monitoring.
