英文摘要：

According to the sensor principle,the label-free optical fiber biosensor can be divided into optical fiber surface plasmon resonance biosensor,optical fiber evanescent wave biosensor and the optical fiber grating biosensor.The basic structure,working principle and characteristics of these three kinds of biosensors,and their application are introduced briefly in this paper.Finally,the development trend of the label-free optical fiber biosensor is prospected.
