An electrochemiluminescence (ECL) biosensor is described for the detection of microRNA (miRNA-155) based on tris(bipyridine)ruthenium(II) functionalized metal organic framework (RuMOF) materials. The material was prepared by a solvothermal method and was found to be stable even in acidic solution. However, it is selectively and sensitively disassembled by Hg(II) ions, resulting in the release of large...
In situ imaging of miRNA in living cells could help us to monitor the miRNA expression in real time and obtain accurate information for studying miRNA related bioprocesses and disease. Given the low-level expression of miRNA, amplification strategies for intracellular miRNA are imperative. Here, we propose an amplification strategy with a non-destructive enzyme-free manner in living cells using catalyzed...
