A voltage modulated electrochemiluminescent(ECL) method is established for highly sensitive detection. In this new strategy, a small voltage is imposed at a constant voltage that could increase ECL intensity from luminol-hydrogen peroxide by ca. 2 times. This ECL intensity shows a good linear relationship with the concentration of hydrogen peroxide in the range of 1 nmol/L—200 μmol/L with a detection limit of 0.1 nmol/L(S/N=3). The results exhibit that the voltage modulated ECL could be an effective way to increase ECL intensity, and more importantly, used to study the electrochemical process at the electrode interface.
