Definition

Surface plasmon resonance (SPR) is one of several optical phenomena known to occur on two-dimensional metal surfaces (typically gold or silver films) when a total internal reflection of incident light occurs at the interface of two different substances, one with a high refraction index and the other with a low refraction index. The SPR biosensor, which exploits the SPR phenomenon, is a label-free and surface-sensitive spectroscopic system, which utilizes measured changes in the local refraction index upon adsorption. This sensor may be applicable to disease diagnostics and high-throughput screening (HTS) in drug discovery, as well as to studies of biomolecular interaction.

Characteristics

Detection Principle of SPR Biosensor

Surface plasmon polaritons (SPPs), which are also referred to more simply as surface plasmons (SPs), are longitudinal and collective oscillations of electrons occurring on a metal–dielectric interface. The frequency of these longitudinal oscillations is...
