摘要
表面增强拉曼光谱(SERS)分析技术是基于拉曼散射现象,通过将被测物质吸附在SERS衬底表面增强其“指纹”信息,以实现痕量检测,具有前处理简单、灵敏度高、操作简单、可实现现场实时无损检测等优点,在食品安全快速检测领域备受关注。文章介绍了各类SERS衬底的特点和局限性,总结了近年来SERS分析技术在食品安全检测领域的研究进展,讨论了其商业应用所面临的挑战,并对其未来发展进行了展望。
Based on Raman scattering phenomenon,surface-enhanced Raman spectroscopy(SERS)detection technology enhances"fingerprint"information of tested substance by adsorbing it on the surface of SERS substrate to achieve trace detection.With the advantages of simple pre-processing,high sensitivity,simple operation,real-time non-destructive detection on site and so on,SERS analysis technology has attracted much attention in food safety rapid detection.The characteristics and limitations of various types of SERS substrates were introduced.The recent research on SERS detection technology in food safety detection was summarized in detail.Finally,this paper discussed the challenges of its commercial application,and prospected the future development.
