Quenching of the electrochemiluminescence of RU-complex tagged shared-stem hairpin probes by graphene oxide and its application to quantitative turn-on detection of DNA.
本文报道了氧化石墨烯(GO)在玻璃碳电极(GCE)表面对三(2,2'-联吡啶)二价钌(Ru(bpy)3^2+)/三正丙胺(TPrA)电化学发光(ECL)体系的高效且稳定猝灭作用。为阐明猝灭机制,作者系统研究了GO、不同还原程度的还原氧化石墨烯(RGOs)以及聚合物包裹GO修饰GCE的电化学和ECL性能。结果表明,GO表面的含氧基团、...
