Biosensor technology is a new -high powerful biological analytical technique, which incorporating a biological or biomimetic sensing element, either connected to or integrated within a transducer system, and harnessing the specificity, sensitivity, small and convenient for use characteristics, have developed rapidly in recent years, and it has been applied in many fields such as health care, food industry and veterinary and husbandry, and become one of the main research items. In this paper, the concept and principles of biosensor, the classification, the research and application in main fields of biosensor were reviewed, the commercial situation, the advantages and limitations of biosensor were addressed, and the prospect of development of biosensor was presented.
