The Surface Plasmon Resonance (SPR) technique is utilized to assess, in real-time, interactions between biomolecules, and in niche surface science applications.hotons are âabsorbedâ and converted to surface plasmons. Since the photons are not reflected, a âshadowâ occurs in the reflected light. Reichert Inc.âs Surface Plasmon Resonance instruments are optically configured to illuminate a spot on the gold surface over a range of angles from 58 to 85 degrees.
