A wireless single-electrode electrochemiluminescence (ECL) system is for the first time designed by coupling single-electrode ECL system with wireless energy transfer. It consists of a wireless energy transfer module, a single-electrode ECL system and a diode. The electric current in this system is supplied through the wireless energy transfer and then rectified by the diode. The potential difference is induced by the resistance of ITO of the single-electrode ECL system, which leads to the ECL reaction of luminol and hydrogen peroxide. With this system, linear range of hydrogen peroxide from 1 to 150 mu M is obtained by photomultiplier tube (PMT) detector with a detection limit of 0.26 mu M. Moreover, visual detection was carried out using a smart phone as detector. And the linear range of hydrogen peroxide was from 10 to 100 mu M. Because of its advantages like low cost, high sensitivity and portability, this wireless single-electrode system has great potential for the applications in on-site detection, drug screening and point of care testing.
