Surface Plasmon-Coupled Raman Scattering and Cell Targeting Using Functional Raman Probe

Abstract

表面等离子体耦合发射(SurfacePlasmon-CoupledEmission,SPCE)是利用金属近场作用范围内的受激分子与金属表面等离子体之间的耦合作用而建立起来的一种新型的界面增强技术。因具有角度分辨性、偏振性、背景抑制作用等优势,SPCE在近年来发展迅速,主要应用于荧光方面,在拉曼散射方面的应用较少且集中于Kretschmann模式的研究。将SPCE技术应用到拉曼散射上,有利于改善拉曼散射的收集效率,提高检测灵敏度。金属膜上的传播表面等离子体(PSP)与金属纳米颗粒上的局域表面等离子体耦合,能进一步增强拉曼散射。同时,功能化的纳米颗粒作为可移动的拉曼活性基底,可进入细胞并提供细胞内...Surface plasmon-coupled emission (SPCE) is a novel near-field enhanced technique based on the coupling between the excited molecules and the surface plasmons on the metallic surface. Owing to its unique properties of high directionality, p-polarization and background suppression, SPCE has been developed rapidly and mainly applied to fluorescence, while it is used less often in Raman scattering and...学位:理学硕士院系专业:化学化工学院_分析化学学号:2052012115146
