中文摘要：

拉曼光谱自20世纪20年代被发现以来,经过近90年的发展,产生了许多分支。其中表面增强拉曼光谱是利用被测物质与粗糙金属表面的相互作用来提高拉曼光谱的信噪比,从而得到敏感度和精确度更高的图谱,可以将样品在不经过预处理的情况下对其进行快速检测。本文综述了表面增强拉曼光谱技术的原理、分类及鉴定特点,总结了该技术在食品、化学、医药、工业、病原等微生物学科的临床应用,进一步阐述了研究该技术的必要性和应用前景,旨在为从事该领域的科研人员提供参考依据。

英文摘要：

Raman spectroscopy has generated many branches during the development for more than 90 years. Surtace enhanced Raman spectroscopy （SERS） improves SNR by using the interaction between tested materials and the surface of rough metal, as to quickly get higher sensitivity and precision spectroscopy without sample pretreatment. This article describes the characteristic and classification of SERS, and updates the theory and clinical application of SERS. It also summarizes the present status and progress of SERS in various disciplines and illustrates the necessity and urgency of its research, which provides rationale for the application for SERS in microbiology.
