摘要
表面增强拉曼光谱(SERS)技术具有适于现场快速分析等优点,从而引起众多分析科学家的关注。但在实际分析过程中,SERS信号易受基体干扰,重现性欠佳,因此SERS技术目前多应用于定性或半定量分析,SERS定量分析技术仍亟待发展完善。随着科技的不断发展,人们对准确度更高的表面增强拉曼光谱定量技术的需求日益强烈。该文综述了目前外标法、内标法和化学计量学定量方法等主流SERS定量分析技术在近年来的研究进展,并展望了SERS定量分析技术的未来发展趋势。
Surface enhanced Raman spectroscopy（SERS） technique has attracted the attention from analysts due to its advantage of potential capability for on-site rapid analysis and so on. However, the SERS signals would be easily influenced by the complex sample matrixes during real analytical processes, acquiring poor reproducibility. Thus, SERS technique is mostly used in qualitative or semi-quantitative analysis projects at present, and reliable SERS quantitative analysis technique still remains to be improved. With the continuous development of science and technology, an increased demand of people for more accurate surface enhanced Raman quantitative techniques is developed. Herein, the research progress of currently popular SERS quantitative analysis techniques is reviewed, including external standard methods, internal standard methods and chemometrics quantitative meth- ods, in recent years. In addition, the development trend of SERS quantitative analysis technology is prospected in the future.
