Dual Amplification on Coordination-Engineered Photogate for Sensitive Organic Photoelectrochemical Transistor Biosensing.
MicroRNA (miRNA) analysis using organic photoelectrochemical transistor (OPECT) biosensors is often limited by insufficient photoelectric transduction efficiency and weak signal amplification. Herein, we develop a coordination heterojunction photogate-enabled OPECT biosensor combined with enzyme-free catalytic hairpin...
