Methods Mol Biol. 2020:2135:237-247. doi: 10.1007/978-1-0716-0463-2_14.

Abstract

The photoelectrochemical (PEC) biosensor, in which light is utilized to excite the photoactive species and current is employed as the detection signal, is a newly appeared yet dynamically developing technique for biological analysis. Based on the assay of DNA binding proteins upon visible light irradiation, a PEC biosensor is constructed for successfully probing a DNA-protein interaction.

Keywords: Cadmium sulfide; DNA–protein interaction; Photoelectrochemical biosensor; Quantum dots; TATA-binding protein.
