ResumoGraphene field-effect transistors are appealing for biosensing applications due to their high charge sensitivity. In article number 1800186, Nesha Andoy, Alexey Tarasov, and co-workers demonstrate label-free detection of a clinically relevant protein – thyroid-stimulating hormone – with a femtomolar detection limit in undiluted serum. This highly sensitive and selective detection in complex samples is facilitated by co-immobilizing antibody fragments and polyethylene glycol on graphene.
