Trap remediation of CuBi2O4 nanopolyhedra via surface self-coordination by H2O2: an innovative signaling mode for cathodic photoelectrochemical bioassay

Hydrogen peroxide spontaneously interacts with the uncoordinated Cu( ii ) on the surface of CuBi 2 O 4 , enabling efficient remedy of trap states, and thereby realizing an innovative cathodic photoelectrochemical detection for Flap endonuclease 1.
