Photoelectrochemical thrombin biosensor based on perylene-3,4,9,10-tetracarboxylic acid and Au co-functionalized ZnO nanorods with signal-off quenching effect of Ag@Ag

本文报道了一种基于3,4,9,10-四羧基芘酸（PTCA）与金纳米颗粒共功能化氧化锌纳米棒（ZnO NRs）光阳极，以及Ag@Ag2S的“信号关闭”淬灭放大效应，构建凝血酶光电化学适配体传感器。PTCA优异的可见光电性能和Au纳米颗粒的表面等离子体共振（SPR）效应显著提高了ZnO NRs的光电流响应。凝血酶与适配体特异性识别后，形...
