Photo-driven self-powered biosensor for ultrasensitive microRNA detection via DNA conformation-controlled co-sensitization behavior†
Abstract
We successfully developed a photoelectrochemical enzymatic fuel cell (PEFC)-based self-powered biosensing platform for microRNA detection via DNA conformation change-controlled co-sensitization behavior, which could offer ultrasensitive detection of microRNA down to 0.05 fM and realize microRNA determination in human serum.
