Surface plasmon resonance (SPR) is a phenomenon occuring at metal surfaces (typically gold and silver) when an. incident light beam strikes the surface at a particular angle. Surface Plasmon Resonance is a phenomenon that occurs when polarized light hits a metal film at the interface of media with different refractive indices. SPR techniques excite and detect collective oscillations of free electrons (known as surface plasmons) via the Kretschmann configuration, in which light is focused onto a metal film through a glass prism and the subsequent reflection is detected (Fig. 1). When electric fields of light are directed at nanoparticles, the surface plasmons become excited and begin to resonate.

We would sincerely appreciate your consideration of our SPR system for your research uses in the cutting-edge nanotechnology field. Principle Jan 10, 2012 In an SPR binding experiment, this refractive index change is brought about by binding of analyte in solution to ligand immobilized on the chip Surface plasmon resonance (SPR) is an optical-based, label-free detection technology for real-time monitoring of binding interactions. Learn more. May 19, 2017 Biosensor chip selection is a critical step in planning a surface plasmon resonance (SPR) experiment. Chip selection depends on the ligand This review describes the principles of surface plasmon resonance microscopy and imaging and discusses recent advances in these methods, in particular, abstract = "A biosensor based on the surface plasmon resonance (SPR) principle was used for kinetic analysis of lectin interactions with different immobilized For a demonstration of the principle, three synthetic, biotinylated polypeptides Imaging surface plasmon resonance, Biosensor, Affinity microarray, Analyte In principle, this can be achieved by measuring the rate of diffusion-limited mass uptake to a sensor surface modified with a receptor designed to only bind the Biomolecular interaction analysis is at the core of many research projects.
To sufficiently describe surface plasmon resonance imaging, the concept of traditional SPR should first be reviewed.

The dispersion curve of the photon and surface plasmon wave must cross each other as shown in Figure 1 .b [ 2 , 20 ] for surface plasmon resonance to occur when the momentum of incoming light is equal to momentum of the plasmons.
