摘 要:表面增强拉曼光谱(SERS)技术由于具备指纹识别、检测极限低、灵敏度高、操作简便、兼具在线与离线检测能力等优势从被发现起就引起了广泛的研究兴趣。SERS技术主要通过制备、加工特殊的基底使得目标检测物的拉曼信号得到指数级增强,有效解决了拉曼散射光远小于弹性散射光的问题,甚至可实现单分子级别的检测。近期,过渡金属硫化物作为一种新兴SERS基底表现出分子兼容性高、抗荧光背景等多种优势,其对拉曼信号的增强机制也与传统贵金属基底不同,因此研究人员从增强机理、结构调控、SERS性能、应用等角度进行了大量的研究。本文总结了过渡金属硫化物SERS的研究进展,简单介绍了SERS基底的发展历程和分类,主要介绍了过渡金属硫化物SERS的增强机理、过渡金属硫化物的结构调控方法与对SERS性能影响、过渡金属硫化物SERS在食品安全检测方面的应用进展,最后对存在的主要问题及应用发展前景进行了总结。Surface enhanced Raman spectroscopy(SERS)technology has attracted widespread research interest since its discovery due to its advantages such as fingerprint recognition,low detection limit,high sensitivity,easy operation,and the ability to detect onlineor offline.It mainly enhances the Raman signal of the target detection object exponentially by preparing and processing special substrates,effectively solving the problem of weak Raman scattering intensity,and even at the single-molecule detection level.Recently,transition metal dichalcogenides(TMDs)based SERS substrates have shown impressive advantages such as high molecular compatibility and anti-fluorescence.Their enhancement mechanism for Raman signals is also different from traditional precious metal substrates.Therefore,researchers have conducted extensive research from the perspectives of enhancement mechanism,structural regulation,SERS performance,and applications.This article summarizes the research progress of TMDs based SERS,by introducing the development process and classification of SERS substrates,the structural control methods and performance,the application progress of transition metal sulfide SERS in food safety.Finally proposes the main problems and application development prospects.
