In situ electro-polymerization of nitrogen doped carbon dots and their application in an electrochemiluminescence biosensor for the detection of intracellular lead ions.
本文报道了一种用于检测细胞内铅离子(Pb2+)的电化学发光(ECL)生物传感器。该传感器以玻璃碳电极(GCE)为基底,通过原位电聚合邻苯二胺(OPD)在电极表面制备氮掺杂碳点(N-CDs)作为发光体,并利用银纳米粒子(AgNPs)连接氨基修饰的捕获DNA(T1)。随后,标记Pd-Au六八面体(Pd@Au HOHs)的互补DNA(T2...
