自组装纳米阵列SERS基底的发展及应用进展

Development and Application of SERS Enhanced Substrate Based on Self-assembled Nano-array Technology

表面增强拉曼散射(SERS)的谱峰窄以及分子指纹特性使其在分析化学、环境检测、生物医药及食品安全等领域具有广泛应用。而稳定、均一、重复性好的SERS活性基底的制备至关重要。自组装法可制备出均一、稳定、高度有序、可控的纳米阵列,提高SERS检测的重现性和灵敏度。本文对自组装纳米阵列技术制备SERS活性基底及SERS的应用进行了综述。

Surface-enhanced Raman Scattering( SERS), due to the characteristics of narrow spectrum and molecular fingerprinting,has been widely used in analytical chemistry,environment,biomedicine,food safety and other fields. It is crucial to prepare a stable,uniform and reproducible SERS-active substrate. Self-assembly method can prepare uniform,stable,highly ordered,controlled nano-arrays,thereby increasing the repeatability and sensitivity of SERS detection. The SERS substrate self-assembled technology and its application were reviewed.
