A Ratiometric Photoelectrochemical Biosensor Based on Polarity Reversal of Photocurrent Caused by Controllable Surface Defect Engineering

Ratiometric photoelectrochemical (PEC) biosensors based on polarity reversal of photocurrent can effectively avoid false positive or negative signals. However, the two different sensing interfaces that generate two photocurrent signals with opposite polarities limit the detection accuracy, and the critical voltage ca...
