SPR can be performed by either cross-linking a given ligand to a sensor chip covalently or utilizing high-affinity non-covalent interactions to secure a ligand in a particular conformation to a chip, both of which have their potential advantages. The simultaneous measurement of surface plasmon resonance (SPR) spectroscopy and surface-enhanced Raman scattering (SERS) on flat metallic surfaces is demonstrated on a relatively simple experimental setup based on the Kretschmann configuration. Surface plasmon resonance (SPR) is one of the commonly used technologies for detailed and quantitative studies of protein-protein interactions and determination of their equilibrium and kinetic parameters. SPR provides excellent instrumentation for a label-free, real-time investigation of protein-protein interactions. Surface plasmon resonance is an excellent method for monitoring changes in the refractive index in the near vicinity of the metal surface.
