Localized surface plasmon resonance is generated by metal nanoparticles, typically gold and silver, as compared to a continuous film of gold as used in traditional SPR. LSPR produces a strong resonance absorbance peak in the visible range of light, with its position being highly sensitive to the local refractive index surrounding the particle.

Utilization of SPR as biosensors to monitor and provide Surface plasmons, also often known in the literature as surface plasmon polaritons (SPPs) or surface plasmon waves (SPWs), are longitudinal charge-density distributions generated at the metal/dielectric interface (typically gold or silver) when light propagates through the metal. 2017-04-20 · In the last two decades, plasmon resonance in gold nanoparticles (Au NPs) has been the subject of intense research efforts. Plasmon physics is intriguing and its precise modelling proved to be challenging. Localized surface plasmon resonance (LSPR) fiber-optic sensors have been widely investigated in recent years for biomolecule analysis [1,2], since the surface metallic nanoparticle arrays are extremely sensitive to the refractive index (RI) variation of the surrounding medium [3,4], which includes but is not restricted to their applications in antigen–antibody interactions [5,6] and biotin The origin of the surface plasmon resonance and synthesis procedures are described.

The LSPR related absorbance intensity and wavelength were shown to be dependent on shape and size of the nanoparticles, and can be further controlled by varying the stoichiometric ratio and aspect ratio of the nanoparticles [37] , [38] . Signal enhancement by gold nanoparticles is caused by several effects such as surface mass increase due to enhanced surface area, larger refractive index changes by the particle mass, themselves, and electromagnetic field coupling between the plasmonic properties of the particles (localized surface plasmon resonance) and propagating plasmons.
