Green light excited ultrasensitive photoelectrochemical biosensing for microRNA at a low applied potential based on the dual role of Au NPs in TiO2 nanorods/Au NPs composites

Abstract

An ultrasensitive photoelectrochemical biosensing strategy for microRNA at a low applied potential was designed based on the robust photocurrent generated by TiO2 nanorods/Au nanoparticles (Au NPs) composites under green light excitation. The dual role of Au NPs dramatically improved the photocurrent, which guaranteed enough sensitivity, leading to the excellent performance in microRNA detection.
