A novel luminol-based bi-potentiostatic electrochemiluminescent (ECL) system has been established. Two potentials were exerted on two working electrodes respectively with a dual-potentiostat More reactive oxygen species and the oxidative intermediate of luminol were generated in the vicinity of the working electrodes during the ECL process and then stronger and constant ECL emission can be obtained through energy transfer between those active species. After optimizing the experimental conditions, it was demonstrated that the developed ECL system provided great potency for quantified assay. (C) 2014 Elsevier B.V. All rights reserved.
