摘要
表面增强拉曼散射(SERS)技术克服了拉曼光谱灵敏度低的缺点,可以获得常规拉曼光谱不易得到的分子结构信息,成为分子甚至单一分子痕量检测的一个重要手段,在生命科学、分析化学等领域得到了广泛的应用。SERS基底是SERS检测中的核心部件,只有少量特殊处理的贵金属才具有较强SERS效应,同时这些传统SERS基底一般都是一次性使用,这给实际使用造成资源的浪费。在简要介绍SERS光谱发展的基础上,重点介绍了近期在可循环SERS基底的制备和应用作一述评,并对可循环SERS基底的研究和发展做了展望。
With the help of Surface-enhanced Raman scattering （SERS） technique, it is easy to acquire information on molecular structures that cannot be obtained by normal Raman spectroscopy, which overcomes the disadvantage of low sensitivity of Raman spectroscopy. Thus, it has become one of the most important methods for the trace detection of molecules and even single molecules, has been widely used in the life science, analytical chemistry and other fields. SERS substrate is the core component in SERS detection, however, only a few noble metal substrates have strong SERS effect, which are usually single-using, leading to the waste of resources in practical use. Herein, the history of SERS is reviewed, and the advance in the preparation of recyclable SERS substrates is highlightened. The discussion underscores the exciting prospect of developing the recyclable SERS substrates.
