Surface plasmon resonance detects changes in refractive index of the surface layer of a solution in contact with the sensor chip. The change in refractive index is caused by variation of the mass on the sensor chip surface owing to interactions of the biomolecules (A,B) . Biacore’s SPR technology is a label-free technology for monitoring biomolecular interactions as they occur. The detection principle relies on surface plasmon resonance (SPR), an electron charge density wave phenomenon that arises at the surface of a metallic film when light is reflected at the film under specific conditions. The first commercially viable surface plasmon resonance (SPR) biosensor was developed by Biacore AB (www.biacore.com) and became available in 1990. Over the past 13 years, we’ve seen explosive growth of the biosensor’s use in both life science and pharmaceutical research (1). Biacore® is a surface plasmon resonance (SPR) based analytical instrument.

PDF) Optimizing the surface plasmon resonance/mass . Surface Plasmon Resonance - BiaCore Biosensor SPR is a universal tool for studying and characterizing macromolecular interaction in a label-free state. The system detects the binding reaction in real time by monitoring changes in mass concentration at the chip surface; the association and dissociation rate constants are determined directly from the reaction traces. SPR occurs when polarized light strikes an electrically conducting surface at the interface between two media. This generates electron charge density waves called plasmons, reducing the intensity of reflected light at a specific angle known as the resonance angle, in proportion to the mass on a sensor surface. Biacore SPR systems are used primarily in pharmaceutical development, quality control, and basic life science research.
