Abstract: Electrochemical biosensors are a rapid qualitative or quantitative detection method that combines sensing technology with immunoassay. In recent years, with the fast development of nanomaterials, electrochemical immunosensors have become promising candidates for application in the field of protein detection with higher sensitivity, portability and specificity. This article focuses on the construction principle of electrochemical immunosensors and on recent progress in the development and application in protein detection of electrochemical immunosensors based on new nanomaterials. Moreover, future directions in this field are also discussed. It is expected to provide technical reference for rapid detection of protein.

Key words: electrochemical immunosensor; novel nanomaterial; protein; detection
