Progress of Evanescent Wave Fluorescence Immunosensors in Environmental Detection

The evanescent wave fluorescence immunosensor, which employs evanescent wave produced in interface of the waveguide when the light transmits on the manner of total internal reflection in the waveguide, is relatively new kind of sensor on the basis of fluorescence immunoassay principle. This sensor has many advantages including strong specificity, high sensitivity, rapid detection, cost-effective and simple operation, which will be widely applied for environmental detection, clinical medicine and food industry. The principle, structure and characteristics of evanescent wave fluorescence immunosensors were covered and the applications of this kind of sensor in environmental detection were introduced.
