Electrochemiluminescence (ECL) of luminol can be allowed to occur in well-mixed solutions of luminol and hydrogen peroxide. However ECL is scarcely applied for quantitative analysis of biochemicals due to low quantum yield in physiological pH. In this work, we evaluated the effect on the ECL intensity of modifying the electrode with cationic polymer. The sensitivity of ECL to hydrogen peroxide concentration at the treated ITO increased dramatically. Results indicate that the cationic polymer adsorbed on the electrode enhances ECL due to probably increasing pH in the vicinity of the electrode surface. However, the cationic polymer also enhanced inhibition of ECL by ascorbic acid, an anionic reducing reagent.
