We have developed sensitive photoelectrochemical (PEC) detection of cysteine using the gold nanoparticles (Au NPs) equipped perovskite Bi4NbO8Cl heterostructure. The Bi4NbO8Cl was prepared by a solid-state reaction, and the Au NPs/Bi4NbO8Cl electrode was made through the electrostatic layer-by-layer self-assembly technique. The Au NPs/Bi4NbO8Cl electrode provided much enhanced photocurrent with a great increase compared to the bare Bi4NbO8Cl electrode and allowed for the plasmon-enhanced PEC detection of cysteine with good performance. It demonstrated rapid response, high stability, wide linear detection range and certain selectivity, implying its great promise in its application. Therefore, the Au NPs/Bi4NbO8Cl heterostructure has provided a promising platform for the development of PEC bioanalysis. More generally, these findings offered an insight into the exploitation of perovskite materials for PEC bioanalytical purposes.
