摘　　要：表面增强拉曼散射(SERS)光谱具有灵敏度高、光谱特征强、受光漂白影响小等特点,在环境、食品和药品、以及生物分析等领域有着广阔的应用前景。目前,SERS光谱技术仅属于定性或半定量分析技术,尚未发展成为一项成熟的定量分析检测技术。本文综述了现有文献中用于提高SERS定量结果准确度的方法以及它们的优缺点,并在此基础上展望了SERS技术在复杂体系中定量分析的发展方向。Due to its exquisite sensitivity,excellent molecular specificity and reduced photobleaching,surface-enhanced Raman spectroscopy has wide potential applications in the fields of food and drug analysis,environmental monitoring and biological detection. However,SERS is only a qualitative or semi-quantitative detection technique at the present stage,and has not yet been widely recognized as a routine quantitative technique. This review discusses the pros and cons of the quantitative surface-enhanced Raman spectroscopic techniques developed so far in the literature,and looks forward to the future trend in this field.
