Technology Overview
Surface Plasmon Resonance is an advanced and highly sensitive optical technology that can measure refractive index changes on a sensor chip’s gold surface due to a change in mass that occurs during a binding event. This change can be used to monitor biological interactions such as the concentration of target molecules, kinetic rates and affinity constants. BiOptix has developed a novel ultra-sensitive detection platform known as Enhanced Surface Plasmon Resonance (E-SPR). E-SPR or phase-based SPR differs from standard surface plasmon resonance detection methods in that it combines the high sensitivity of SPR with the high stability and lower noise of common path interferometry.
