摘要
表面增强拉曼散射(Surface Enhanced Raman Scattering,SERS)是一种振动光谱技术,可直接识别目标分析物。在分析应用中,SERS信号的重现性极其重要,而这在很大程度上取决于SERS基底结构的均匀性。目前,SERS基底的重现性一直是制约该技术在分析测试中广泛应用的瓶颈,规则排列的纳米结构构成的有序化SERS基底的可控制备是该领域发展的前沿和趋势。本文就SERS基底的有序化制备方法及其应用进行了总结,分析了自组装法、光刻技术和模板辅助法所制备的有序SERS基底的特征、有序性形成原理和在分析测试中应用的可行性,为拓展SERS的实际应用提供一定的参考。
Surface Enhanced Raman Scattering(SERS)is a vibration spectroscopy technology,which can directly identify target analytes and has a wide range of applications in chemistry,physics,materials,biomedicine and other fields.Ordered SERS substrate refers to the SERS substrate composed of regularly arranged nanostructures,which has good uniformity and reproducibility.In this review,surface enhanced Raman scattering and SERS substrates are introduced,and the self-assembly method,lithography technology and template-assisted method for preparing ordered SERS substrates are emphatically described.
