Surface P[SURFACE PLASMON RESONANCE]
Surface plasmon resonance (SPR) is a phenomenon occurring at metal surfaces(typically gold and silver) when an incident light beam strikes the surface at a particular angle.Depending on the thickness of a molecular layer at the metal surface,the SPR phenomenon results in a graded reduction in intensity of the reflected light.Biomedical applications take advantage of the exquisite sensitivity of SPR to the refractive index of the medium next to the metal surface, which makes it possible to measure accurately the adsorption of molecules on the metal surface an their eventual interactions with specific ligands. The last ten years have seen a tremendous development of SPR use in biomedical applications

SURFACE PLASMON RESONANCE
ABSTRACT
Surface plasmon resonance (SPR) is a phenomenon occurring at metal surfaces(typically gold and silver) when an incident light beam strikes the surface at a particular angle.Depending on the thickness of a molecular layer at the metal surface,the SPR phenomenon results in a graded reduction in intensity of the reflected light.Biomedical applications take advantage of the exquisite sensitivity of SPR to the refractive index of the medium next to the metal surface, which makes it possible to measure accurately the adsorption of molecules on the metal surface an their eventual interactions with specific ligands. The last ten years have seen a tremendous development of SPR use in biomedical applications.
The technique is applied not only to the measurement in real time of the kinetics of ligands receptor interactions ...
