Surface plasmon resonance (SPR) is a phenomenon that occurs where electrons in a thin metal sheet become excited by light that is directed to the sheet with a particular angle of incidence, and then travel parallel to the sheet.

Surface Plasmon Resonance (SPR) is an optical technique used to measure molecular interactions in real time. SPR can occur when plane-polarized light hits a metal film under total internal reflection conditions. SPR signal is directly dependent on the refractive index of the medium on the sensor chip.

2020年10月15日 · A Surface Plasmon Resonance (SPR) sensorgram, which is a plot of SPR response vs. time generated from an SPR instrument, can reveal whether there is a binding event between an analyte (e.g. antibody) and a ligand (e.g. protein) and whether the binding is specific.
