Thioredoxin Reductase-Mediated Reaction Evokes Surface Polarization Effect on BiOIO: Toward a New Sensing Strategy for Cathodic Photoelectrochemistry.

We have witnessed the fast progress of cathodic photoelectrochemistry over the past decades, though its signal transduction tactic still lacks diversity. Exploring new sensing strategies for cathodic photoelectrochemistry is extremely demanding yet hugely challenging. This article puts forward a unique idea to incorporate an enzymatic reaction-invoked surface polarization effect (SPE) on the surface of BiOIO to implement an innovative cathodic photoelectrochemical (PEC) bioanalysis.
