Abstract：

By the advantages of electrochemiluminescence (ECL) technology, such as high sensitivity, high controllability, and rapidity, it has become a hot spot in the field of analytical chemistry in recent years. However, in the absence of coreaction reagent or other signal amplification methods, the response signal of the ECL sensor is often weak. Therefore, building the signal amplification technique to amplify the response signal of the ECL sensor has become the to the further development of this technology. According to many reports, the signal amplification and sensitivity of ECL sensors can be effectively improved by constructing new signal amplification strategies based on nanomaterials. Here, this paper mainly discusses the application and development of signal amplification strategies based on nanomaterials for ECL biosensors.
