Abstract

Electrochemiluminescence (ECL) has broad application in the fields of environmental monitoring and biological analysis due to its intrinsic advantages such as excellent versatility, good detection sensitivity, and high specificity. The intensity of ECL can be influenced by temperature variation in the ECL quantum efficiency and the rate of electrochemical reaction. However, traditional temperature control is commonly realized through bulk solutions heating, which is complicated and unfavorable for detection when the volatile and thermally unstable materials existed. In order to address these problems, electrically heated electrodes are used to adjust the temperature desired. The major character of this technique lies in the heating electrode up, while leaving the bulk solution at ambient temperature, which promotes the performance of the sensor by affecting the thermodynamic and kinetic parameters of the reaction, and further improves the sensitivity of the ECL detection. Moreover, the background signal, and the volatile and thermally unstable substances that are susceptible to temperature will not be affected. The contamination on the surface of the electrode can also be easily removed by electrical heating, thereby the reproducibility of ECL sensor is improved. As a whole, this article aims at reviewing the research progress of ECL sensors based on the electrically heated electrode in the analysis and detection of target molecules, summing up the main problems in the practical determination, and providing an outlook in the future development trend of this technology.
