Surface plasmon resonance combined with conventional techniques

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 (electrochemical techniques such as cyclic voltammetry and stripping voltammetry; optical techniques including fluorescence spectrometry and infrared spectrometry; mass spectrometry; quartz crystal microbalance 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 interferometry-surface plasmon resonance are reviewed in details.
