Abstract

N-Hydroxysuccinimide (NHS) and N-hydroxysulfosuccinimide (NHSS) were exploited as efficient coreactants for cathodic Ru(bpy)32+ electrochemiluminescence (ECL) in neutral medium. The developed systems showed stronger ECL signals than that of the classic Ru(bpy)32+-H2O2 system and have been exploited for sensitive "turn-on" type ECL detections of methyl blue and Hg2+.
