Surface Plasmon Resonance (SPR) is a physical process that can occur when plane-polarized light hits a thin metal film under total internal reflection conditions . Total internal reflection When a light beam hits a half circular prism, the light is bent towards the plane of interface, when it is passing from a denser medium to a less dense one.

James M. Davison, Se hela listan på cytivalifesciences.com 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 Surface plasmon resonance is an excellent method for monitoring changes in the refractive index in the near vicinity of the metal surface. This video explains what Surface Plasmon Resonance technology is, how it is used to detect small molecules and their interaction with other proteins.For more Surface plasmon resonance refers to the electromagnetic response that occurs when plasmons are oscillating with the same frequency on the surface of a material. As these plasmons oscillate at specific resonant frequencies, they move with periodic driving forces that can become large amplitude oscillations when they interact. 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. The excitation of surface plasmons is frequently used in an experimental technique known as surface plasmon resonance (SPR).
