Dopamine detection based on its quenching effect on the anodic electrochemiluminescence of CdSe quantum dots

Abstract

Anodic electrochemiluminescence (ECL) of CdSe quantum dots (QDs) in a neutral system was for the first time observed at a relatively low potential by using sulfite as a co-reactant to produce the ECL emission at an indium tin oxide (ITO) electrode, which could be used for the sensitive detection of ECL quenchers using dopamine (DA) as a model molecule.
