DNA nanomachine-based regenerated sensing platform: a novel electrochemiluminescence resonance energy transfer strategy for ultra-high sensitive detection of microRNA from cancer cells.

DNA纳米机器的构建对DNA纳米结构发展意义重大，但实际应用仍处早期；一步再生传感平台仍是现实挑战。本文报道了新型电化学发光共振能量转移（ERET）策略，以小分子染料Alexa Fluor 488（AF488）为供体、CdSe@ZnS量子点（QDs）为受体，该体系更易进入细胞，用于构建基于DNA纳米机器的再生生物传感器，无酶超灵敏检...
