Term Name:	surface plasmon resonance evidence
Synonyms:	SPR evidence
Definition:	A type of physical interaction evidence based on real-time, rapid plasmon generation on the interface between a planar surface and vacuum that measures changes in refractive index close to the sensor surface when an analyte and its immobilized ligand bind to observe and characterize molecular interaction.
