What is Surface Plasmon Resonance (SPR)? Similar to BLI, SPR is also a label-free binding technique that can measure binding kinetics of biomolecular interactions in real time. Instead of using a tip, a sensor chip which maintains gold coated on a glass substrate with the desired surface chemistry is used to immobilize one of the binding partners onto the surface.

Surface Plasmon Resonance and Nanoparticles . Nanoparticles are of interest to the scientific community for a multitude of reasons including their large surface area to volume ratio which makes them very reactive to external stimuli quickly, the fact that they operate on a quantum mechanics scale, and because the nanoscale is the level at which many biological processes occur.
