Abstract:

In this paper, an ECL detection system equipped with an electrically heating controlled cylindrical microelectrode (HME) was used to study the ECL behavior of lucigenin. The ECL intensity of lucigenin would be increased at elevated electrode temperature but the noise had not been increased. It was found that ECL intensity at higher temperature of electrode surface (80 °C) was more than two magnitudes stronger than that at the room temperature (22 °C). The detection limit for ECL of lucigenin on a HME is much lower than that on an electrode without heating, based on which, it is possible to establish a more sensitive method for measurement of ECL by using a HME. The heating of electrode has been used to renew the electrode, which avoid the tedious work for refreshing the electrode surface. The reproducibility of lucigenin ECL system at HME is satisfactory. © 2006 Elsevier B.V. All rights reserved.
