表面增强拉曼光谱（SERS）是一种重要的光谱分析方法，具有灵敏度高、操作简单、检测速度快、选择性好等优点，其性能高度依赖活性等离子体基底的性质。纤维素是地球上最丰富的生物聚合物，具有廉价易得、可再生及绿色环保等性质。因此，越来越多的纤维素材料被用于制备SERS的基底。从电磁场增强和化学增强两方面阐述了SERS增强机理，并介绍了纤维素材料的种类以及制备SERS基底的方法；综述了纤维素SERS基底在生物分析、水质评估、食品安全、环境污染及染料识别等方面的应用，并展望了未来的研究方向。

Surface?enhanced Raman spectroscopy (SERS) is an important spectroscopic method with the advantages of high sensitivity, simplicity, fast detection and good selectivity. The performance of SERS is highly dependent on the properties of the enhanced substrate. Cellulose is one kind of the most abundant biopolymer in the world, which is inexpensive, readily available, renewable and environmental friendly. Therefore, cellulosic materials are usually employed to prepare SERS substrate. In this review, the enhancement mechanism of SERS was firstly disscussed, and then the fabrication of cellulose SERS substrates were introduced. The applications of cellulose SERS substrates were reviewed in biological analysis, water quality assessment, food safety and environmental pollution, and dye identification.
