Biosensor is a kind of emerging sensor, it consists of biological sensitive materials as recognition element (including enzymes, antibodies, antigens, microorganisms, cells, tissues, nucleic acids, and other bioactive substances), appropriate physical and chemical transducer (such as oxygen electrode, light tube, field effect tube, piezoelectric crystal, etc.), and signal amplification device. Compared with traditional detection devices, biosensor has many advantages, such as good specificity, easy operation, simple equipment, rapid and accurate measurement, wide application range, etc. Therefore, it has been widely applied in environmental monitoring, food industry, early medical diagnosis, and other aspects. Our group is devoted to the development of various biosensors for the early diagnosis of diseases.
