Electrochemiluminescence (ECL), the generation of an optical signal triggered by an electrochemical reaction. ECL has recently become an important and valuable detection method and been applied in many fields due to its inherent advantages such as high sensitivity, high selectivity, very low background signal, simple instrumentation and low cost. ECL immunosensor, the combination of very sensitve ECL detections with extremely selective biological recognition pattern immunoassays. Thus the development of a h...
