Band bending-induced polarity switching in heterojunctions for self-validated aptasensor toward fg-level chloramphenicol detection.

Although bias-regulated photocurrent polarity switching has been preliminarily explored for self-verifying photoelectrochemical (PEC) sensing, achieving stable bipolar photoresponses with a clearly defined interfacial charge-transfer mechanism remains challenging. Herein, a P-N covalently bridged red phosphorus (RP)/g-...
