Abstract

In this work, a novel photoelectrochemical biosensing strategy was designed for cell assay under 630 nm (red light) excitation. WS₂/Au NP nanocomposites were prepared as a photoelectrochemical biosensing substrate. The localized surface plasmon resonance effect of Au NPs tremendously improved the photoelectric conversion efficiency and enhanced the detection sensitivity.
