摘　　要：基于表面增强拉曼散射(SERS)的光纤传感器结合了光纤与表面增强拉曼散射效应,具有普通传感器无法比拟的优点。但是,应用普通光纤将带来诸如背景干扰与吸收、光纤自身的荧光效应及拉曼散射等缺点。为解决这一问题,将光子晶体光纤与表面增强拉曼散射效应相结合,称为基于表面增强拉曼散射的光子晶体光纤(PCFs)传感器,具有高灵敏度、抗干扰、结构简单、光路可弯曲及对待测物影响极小等优点。介绍了表面增强拉曼散射效应、光子晶体光纤和基于表面增强拉曼散射的光子晶体光纤传感器的发展现状,主要包括原理、几何结构和在生物传感中的独特应用,总结了此新型传感器的发展趋势,讨论了下一步亟需解决的问题。Optical fiber surface enhanced Raman scattering （SERS） sensors, which achieve optical fiber sensing based on SERS effect, have several particular advantages. However, the use of conventional fiber has brought optical fiber SERS sensors some drawbacks, such as background absorption and interference, fluorescence effect and Raman scattering from the fiber itself. The adaptive SERS sensors are developed to solve these problems, which is at least partially promised by the newly emerging photonic crystal fibers （PCFs）. The PCFs SERS sensors composed of PCFs and SERS, have several advantages such as high sensitivity, interference-immunity, simple geometry, light path flexibility, and little dependence on analyte. This review shows the development and the state-of-art of SERS, PCFs, and PCF sensors based on SERS, mainly including theory, geometries, and biosensors applications. Although the recent developments is fast, there still exist a few problems that should be addressed, and particularly, the trend of PCF sensors based on SERS is discussed.
