Photoelectrochemical detection of microRNAs based on target-triggered self-assembly of energy band position-matched CdS QDs and C
本文报道了一种基于目标 microRNA(miRNA)触发催化发夹组装(CHA)反应的高灵敏光电化学生物传感器,用于 miRNA 检测。首先将金纳米粒/碳氮化纳米片(AuNPs/C3N4 nanosheets)固定在玻碳电极(GCE)工作电极上,再通过 Au–S 键合负载发夹探针1(H1),并用 6-巯基己醇(MCH)封闭未结合位点...
