In Situ Ion-Exchange-Mediated Dynamic Nanointerface Reconfiguration for Polarity-Switchable Photoelectrochemical–Photothermal Biosensing
Conventional photoelectrochemical (PEC) systems typically rely on static semiconductor interfaces that merely translate biomolecular recognition into amplitude modulation of the pre-existing photocurrent, thus limiting their analytical robustness and self-validation capabilities. Herein, we report in situ ion-exchang...
