Core–shell Au@PtAg modified TiO2–Ti3C2 heterostructure and target-triggered DNAzyme cascade amplification for photoelectrochemical detection of ochratoxin A

Efficient charge separation and utilization are critical factors to obtain a high initial signal in photoelectrochemical (PEC) aptasensor. Reports demonstrate that constructing metal/semiconductor Schottky junction can effectively improve the charge separation efficiency. Herein, a photoelectrode Au...
