Electrochemiluminescence (ECL) on bipolar electrode (BPE) is a sensitive, portable, and low-cost approach which has been employed to detect DNA and proteins. Here, we develop an ultrasensitive method for intracellular mRNA assay based on mRNA-mediated reporter DNA liberation and Ru(bpy)3 2+-conjugated silica nanoparticles (RuSi@Ru(bpy)3 2+) tag-based signal amplification.
