基于黏性末端链置换（TMSD）非酶扩增技术构建了一种简单、高灵敏的电化学发光/电化学比率传感方法用于miRNA的检测。本方法以修饰在电极上的亚甲基蓝（MB）产生的EC信号作为内参比信号，并将Ru（phen）32+嵌入到通过分支杂交链式反应（bHCR）产生的DNA纳米微粒中作为ECL探针。目标物存在时，MB脱离电极表面并使ECL信标修饰在电极上，从而使EC信号减弱，ECL信号增强，采用ECL和EC信号比值（ECL/EC）作为输出信号，降低了潜在干扰，提高了传感器的重现性和灵敏度。体系的ECL/EC比值与miRNA-21的浓度在10 fmol/L～500 pmol/L范围内具有良好的响应，检出限为6.5 fmol/L。与单一使用ECL信号的方法相比，在测定1 pmol/L的miRNA目标物时，响应信号的相对标准偏差从8.2%下降到4.1%。本方法成功应用于复杂细胞样品中miRNA-21的检测。
