Graphene 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.
