%X 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.
