Target-induced electronic switch for ultrasensitive detection of Pb2+ based on three dimensionally ordered macroporous Au-Pd bimetallic electrode.

本文提出一种基于三维有序大孔（3DOM）Au–Pd双金属电极和靶标诱导亚甲基蓝-单壁碳纳米管（MB-SWCNTs）信号报告的选择性、灵敏安培检测Pb2+策略。通过在3DOM Au–Pd电极上固定捕获探针DNA构建DNA生物传感器；暴露于Pb2+后，与负载于MB-SWCNTs加合物上的报告DNA杂交，产生可测电化学信号。由于3DOM ...
