SPR Spectrometers

Surface Plasmon Resonance (SPR) spectrometers are devices used to study the interactions between biomolecules, such as proteins and DNA, in real-time. They rely on the SPR phenomenon, where light is coupled with surface plasmons on a thin metal film, leading to changes in reflectivity due to biomolecular binding events occurring on the sensor surface. By monitoring these changes, SPR spectrometers can provide information about the kinetics, affinity, and specificity of biomolecular interactions. These instruments find widespread use in fields such as drug discovery, molecular biology, and biochemistry for applications including drug screening, protein-protein interactions, and antibody-antigen binding studies.
