(Invited) Wireless Electrochemiluminescence Devices

Abstract

Traditional electrochemical systems generally require the direct connection of working electrode with potentiostat. They often employ two electrodes (a working electrode and a counter electrode) or three electrodes (a working electrode, a counter electrode, and a reference electrode) for a single electrochemical experiment. Different from traditional electrochemical systems, wireless electrochemical systems do not require the direct connection of working electrode with potentiostat. Conventional ipolar electrochemical system is a well-known wireless electrochemical system. It exerts potential control over electrolyte solutions with driving electrodes and redox reactions occur at the two opposite poles of the bipolar electrode. This enables simultaneous control of many bipolar electrode arrays with only two driving electrodes for multiplex experiments.Electrochemiluminescence, also called electrogenerated chemiluminescence (ECL), is light-emitting phenomenon generated from electrochemical reaction. The combination of bipolar electrochemical systems with ECL enables facile multiplex analysis.We present here several new wireless ECL systems, including wireless electrochemiluminescence, single-electrode ECL system, and wireless single-electrode ECL system [1-5].AcknowledgmentWe are grateful for financial support from the National Key Research and Development Program of China (No. 2016YFA0201300), National Natural Science Foundation of China (Nos. 21804127,21874126,21675148), the Chinese Academy of Sciences (CAS)-the Academy of Sciences for the Developing World (TWAS), and President’s Fellowship Program, the CAS President's International Fellowship Initiative (PIFI) project.
