Surface Plasmon Coupled Emission for Polymer Films

Abstract

表面等离子体耦合发射荧光(SPCE)是利用激发态的荧光团和金属表面等离子体的耦合近场作用而建立起来的一种新型的表面增强荧光技术,具有角度定向性、波长分辨性、距离依赖性、信号偏振性和背景抑制作用等多种独特的光学特性,在化学分析、生物传感、细胞成像等领域中显现出广阔的应用前景。聚合物刷已经成为一种典型的软物质界面材料,由于其化学组成与空间构型的不同,对pH值、温度、溶剂、光和离子等多种环境刺激会产生响应,促使表面形貌、厚度或润湿性发生变化。将聚合物刷受刺激后产生的厚度变化特性与SPCE的距离依赖性相结合,可以制备各种用途的传感器。Kretschmann(KR)模式SPCE荧光的研究利用尚少。本文在...Surface plasmon coupled emission (SPCE) technique, based on the near-field interaction between fluorophores and surface plasmons on metal surfaces, has attracted increasing attention in sensor technology, bioanalysis, and cell imaging as it displays unique optical properties like strongly directional emission, unique polarization, wavelength resolution, thickness dependence and background suppress...学位:理学博士院系专业:化学化工学院_化学生物学学号:2052009015330
