Surface plasmon resonance refers to the electromagnetic response that occurs when plasmons are oscillating with the same frequency on the surface of a material. As these plasmons oscillate at specific resonant frequencies, they move with periodic driving forces that can become large amplitude oscillations when they interact.
Surface Plasmon Resonance - BiaCore Biosensor SPR is a universal tool for studying and characterizing macromolecular interaction in a label-free state.
Learn more about this technique in the Technology pages. Surface plasmon resonance (SPR) biosensors have rapidly become a standard tool within the pharmaceutical and biotechnology industries. Label-free, real-time measurements are the calling card for this technology, which can be used to monitor the interactions of nearly any molecular system. To successfully deploy plasmonic sensors, scaled-down analytical devices based on surface plasmon resonance (SPR) and localized surface plasmon resonance (LSPR) must integrate optics, plasmonic materials, surface chemistry, fluidics, detectors and data processing in a functional instrument with a small footprint.
