Research progress of enzyme-based biosensors in rapid detection

Enzyme-based biosensor is a biosensor with enzyme as bio-identification component. It has the advantages of high sensitivity, strong specificity, low detection limit, good selectivity, simple operation, easy portability and continuous online monitoring. It is one of the earliest commercially available biosensors. At present, enzyme-based biosensors have been widely used in various fields, including environmental monitoring, food safety testing, and biomedical testing. With the increase of environmental pollution and food safety, the demand for on-site rapid detection technology is increasing. Therefore, the study of enzyme-based biosensors is of great significance. This paper introduced enzyme-based biosensors, expounded the related concepts and principles of enzyme-based biosensors, and summarized the research status of electrochemical enzyme-based biosensors, optical enzyme-based biosensors and other enzyme-based biosensors in rapid detection, and prospected the future research direction of enzyme-based biosensor.
