Wireless electrochemiluminescence with disposable minidevice.

Wireless electrochemiluminescence system based on the wireless energy transmission technique has been demonstrated for the first time. It has a disposable transmitter and a coiled energy receptor. The coiled energy receptor is smartly used as the electrode. The wireless electrochemiluminescence system has been used to detect hydrogen peroxide with good sensitivity, featuring advantages of easy manipulation, low cost, and small size. The handy and cheap wireless electrochemiluminescence device can use laptops as a power supply. It is promising for the development of portable or disposable electrochemiluminescence devices for various applications (e.g., such as point of care testing, field analysis, scientific research, and chemical education). These advantages enable one to integrate many wireless electrochemiluminescence minidevices with screen printing coiled electrode arrays in microwell plates and charge-coupled devices (CCD) cameras to develop electrochemiluminescence high-throughput screening systems with broad applications in clinical analysis, drug screening, and biomolecular interaction studies.
