Abstract Recent research has demonstrated the potential of photogating in regulating characteristics photoelectrochemical transistors. Here it is reported graphene transistor (GPECT) with dual‐directional signal‐on biosensing as exemplified by channel gated p/n‐type metal–organic frameworks (MOFs) upon light illumination toward aptasensing. Due to shift Dirac point induced MOFs, operation mutually verifiable dual readout could be achieved. For aptasensing, assistance biocatalytic precipitation reaction, such a device validated for highly sensitive detection thrombin limits low 5.2 and 0.1 f m , respectively. This study demonstrates not only general protocol GPECTs but also unique novel optoelectronics.
