Electrochemiluminescence based detection of microRNA by applying an amplification strategy and Hg(II)-triggered disassembly of a metal organic frameworks functionalized with ruthenium(II)tris(bipyridine).

本文报道了一种基于三(联吡啶)钌(II)功能化金属有机框架（RuMOF）的电化学发光（ECL）生物传感器，用于检测microRNA-155（miRNA-155）。该RuMOF材料通过溶剂热法制备，在酸性溶液中保持稳定，但可被Hg(II)离子选择性和灵敏地解组装，从而释放大量Ru(II)(bpy)3离子并产生强ECL信号。结合离子选择...
