英文摘要:

      In recent years, due to their advantage of rapid detection, easy-to-use, high sensitivity, low cost and so on, biosensors have been widely used in clinical test, environmental monitoring, etc. The biosensors have become more and more prominent in food safety, especially in rapid detection of pathogenic microorganism. In this paper, on the basic of both immunological recognition and nucleic acid recognition several biosensors methods for rapid detection of foodborne pathogenic Escherichia coli O157:H7 and their new progress were briefly reviewed. Finally, the existing problems and the research prospects of biosensor were also discussed.
