摘要
表面增强拉曼散射(SERS)技术作为一种分析手段,因其高灵敏度、高选择性、及对样品的非破坏性等,在生物医药、环境检测、分析化学及食品安全等领域获得了广泛应用。金属纳米颗粒阵列因具有较强的局部表面等离子共振效应,能构造出高性能的SERS基底。自组装技术作为可制备出高度有序、可重复性高且结构可控的纳米阵列的方法,迄今仍是SERS基底构造研究领域中的热点。简单介绍了自组装技术的方法及其在SERS基底制备中的发展及应用,并对其未来发展趋势做出展望。
Surface-enhanced Raman scattering （SERS） has been extensively applied in biomedicine, environ- mental sciences, analytical chemistry and food safety due to a lot of obvious advantages, including its high sensitivity and repeatability, excellent selectivity, non-destructive and so on. Highly-ordered metal nanopartiele arrays can serve as high quality SERS substrate owing to their strong localized surface plasmon resonance （LSPR） under most of the commonly-used lasers. Self-assembly is a significant method in array fabrication and has attracted increasing attention in SERS study. This paper gives a brief introduction of self-assembly method and its development in SERS substrate research. This summary is hoped to represent an intelligible outlook for fresh researchers in this field.
