Surface Plasmon Resonance is a phenomenon that occurs when polarized light hits a metal film at the interface of media with different refractive indices. Surface Plasmon Resonance (SPR) is a proven, label-free biosensor technique for studying interactions between all classes of biomolecules and biochemical mechanisms in real time. With SPR, you can answer questions including: How fast do molecules associate and dissociate? How strong is the interaction between molecules (affinity)?

J Appl Lab Med 2018;2:725-36. Surface plasmon resonance, or SPR, is the resonant oscillation of plasmons at a metal-dielectric interface stimulated by incident light. It causes a reduction in the intensity of light reflected from an electrically-conducting surface at the interface of two media. 2018-06-21 · The surface plasmon resonance of spherical NPs is essentially located in the visible wavelength, mostly in the range of 500–600 nm, confining the scale of applications. However, the nanoarchitecture with anisotropy presents two plasmon resonance bands corresponding to the transverse and longitudinal resonance modes such as nanorods [ 13 – 15 ], multispiked nanostar [ 16 , 17 ] and A study of the size dependent blue- and red-shift of the plasmon band of silver nanoparticle films in aqueous solution is reported. A detection scheme, where the particle size is continuously decreased by means of controlled dissolution, while measuring the plasmon band position by UV–vis absorption spectroscopy is used.

Surface Plasmon Resonance Summary Surface Plasmon Resonance, or SPR, is a method by which researchers can study the interactions between two (or multiple) proteins via the activity of surface plasmons. Surface plasmons are oscillating electrons on the surface of a metal, which in many cases is gold due to its high conductivity.
