The electrochemiluminescence biosensor combines the specificity, accuracy, fast response of the biosensor and the high controllability, high sensitivity, low background signal of electrochemiluminescence technology. Therefore, it is widely used in clinical analysis, environmental analysis, food analysis and other fields. When constructing an electrochemiluminescence biosensor, there must be some relationship between the analyte concentration and the output electrochemiluminescence signal. In order to achieve sensitive detection of analytes, the use of an effective signal output mode is the key to construct an electrochemiluminescence biosensor. In recent years, in order to gradually improve the performance of electrochemiluminescence biosensors, researchers have developed different signal output modes. This paper mainly reviews several signal output modes commonly used in the construction of electrochemiluminescence biosensors in recent years.
