Surface plasmon resonance is the resonant oscillation of conduction electrons at the interface between negative and positive permittivity material stimulated by incident light. SPR is the basis of many standard tools for measuring adsorption of material onto planar metal surfaces or onto the surface of metal nanoparticles. It is the fundamental principle behind many color-based biosensor applications, different lab-on-a-chip sensors and diatom photosynthesis.

It causes a reduction in the intensity of light reflected from an electrically-conducting surface at the interface of two media. The “resonance condition”, or wavelength at which the least light is Surface Plasmon Resonance (SPR) is a physical process that can occur when plane-polarized light hits a thin metal film under total internal reflection conditions . Total internal reflection When a light beam hits a half circular prism, the light is bent towards the plane of interface, when it is passing from a denser medium to a less dense one. At this so-called ‘resonance angle’, θ, the photons in the light beam have a momentum (vector with magnitude and direction) equal to the momentum of the surface plasmons, and the photons are converted into plasmons.

To sufficiently describe surface plasmon resonance imaging, the concept of traditional SPR should first be reviewed. It should be noted that the OpenSPR TM uses localized surface plasmon resonance (LSPR), a principle that is covered below.

Surface Plasmon Resonance: Optical Principle When the incoming light is reflected on the interface of about 50nm thick metal layer through a prism, at a certain angle of incidence in total internal reflection, the characteristic light absorption (attenuation of reflected light) can be observed. This is the Surface Plasmon Resonance (SPR) phenomena.

While MP-SPR provides same kinetic information as SPR, it provides also structural information. Hence, MP-SPR measures both surface interactions and nanolayer properties. 6. 6 Principle  Surface Plasmon Resonance :- quantum optical electrical phenomenon from the interaction of light with a metal surface 6 (Zeng, 2006) 7.

Surface plasmon resonance: principles, methods and applications in biomedical sciences Patrick Englebienne∗, Anne Van Hoonacker and Michel Verhas Free University of Brussels, Department of Nuclear Medicine, Brugmann University Hospital, Place van Gehuchten 4, B-1020 Brussels, Belgium Abstract.

SPR is the basis of many standard tools for measuring adsorption of material onto planar metal surfaces or onto the surface of metal nanoparticles. It is the fundamental principle behind many color-based biosensor applications, different lab-on-a-chip sensors and diatom photosynthesis. Principle and Protocol of Surface Plasmon Resonance (SPR) 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 (SPR) allows real-time, label-free detection of biomolecular interactions. SPR occurs when polarized light strikes an electrically conducting surface at the interface between two media. This generates electron charge density waves called plasmons, reducing the intensity of reflected light at a specific angle known as the resonance angle, in proportion to the mass on a sensor surface.
