Electron Acceptors Co-Regulated Self-Powered Photoelectrochemical Strategy and Its Application for Circulating Tumor Nucleic Acid Detection Coupled with Recombinase Polymerase Amplification.

自供电生物传感器因可在零偏压下产生信号而备受关注，但通常要求材料本身具备自供电性能。本文提出通过分子调控将非自供电光电化学体系转化为自供电体系。作者以亚甲基蓝（MB）和对硝基苯酚（p-NP）作为电子受体，对金纳米粒子负载硒化锌纳米片修饰金电极（AuNPs@ZnSeNSs/GE）的光电化学响应进行共调控。该电极在缓冲液中0 V光电流较...
