Ag NPs-based SERS substrates with high stability and sensitivity for practical applications

Abstract

表面增强拉曼光谱(surfaceenhancedRamanspectroscopy,SERS)因具有单分子水平的高灵敏度,指纹图谱的高能量分辨率,衍射极限的空间分辨率和水环境友好等特点,在表面科学、分析科学和生物医学等方面获得了广泛的应用。随着便携式拉曼光谱仪器的问世,SERS在食品安全、环境监测、国防和公共安全等领域的应用前景也越发为研究者所关注。然而,迄今为止,SERS技术通常仅局限于这些领域的实验室基础研究,对于在实际体系中的应用还存在着许多问题。特别是如何获得高灵敏、高稳定、高重现性和易商品化的SERS基底,已成为SERS领域的热点和重点之一,是SERS面向实际应用的基石和瓶颈。 因...Surface enhanced Raman spectroscopy has a wide application in fields such as surface science, analytical science and biomedicine for its high sensitivity up to single molecule level, high-energy resolution of fingerprint spectra, spatial resolution nearing diffraction limit and little interference from water and so on. With the advent of portable Raman spectrometer, SERS has attracted much attenti...学位:工学硕士院系专业:化学化工学院_应用化学学号:2052012115158
