表面等离子体波共振(SPR)是被入射电磁波所激发、存在于金属和电介质界面上电荷密度振动的谐振波。SPR是一种消逝场光学成功应用的典范,它具有体积小、分辨率高、无需标记、抗电磁干扰能力强等特点。本文介绍了SPR与电化学方法(循环伏安法、洛出伏安法)、光学方法(荧光光谱、红外光谱)、质谱和石英晶体微天平等其它常规检测技术联用的研究进展,与其它常规方法联用能进一步提高分析能力,可弥补彼此的不足。本文还特别详细说明了部分电化学方法、干涉测量法与表面等离子体波共振联用的优势及不足。
Surface plasmon resonance (SPR) is used to describe the excitation and propagation of electromagnetic waves along the metal-dielectric interface. SPR is one of the successful applications for evanescent wave, which has the features of small volume, high resolution, label-free analysis and the strong capability of anti-electromagnetism etc. SPR combined with other conventional techniques (dectrochemical techniques such as cyclic vohananetry and stripping voltammetry; optical techniques including fluorescence spectrometry and infrared spectrometry; mass spectrometry; quartz crystal microbalanee etc. ) are discussed, which can further improve the ability of analysis and is complement for each other. In particular, the advantage and disadvantage of electrochemical surface plasmon resonance and interferometrysurface plasmon resonance are reviewed in details.
