LSPR : localized surface plasmon resonance Localized surface plasmon: a photon-driven coherent oscillation of the surface conduction electrons in a material with negative real and near-zero imaginary dielectric constant SERS : surface-enhanced Raman scattering INTRODUCTION Materials that possess a negative real and small positive imaginary dielectric constant are capable of supporting a surface plasmon resonance (SPR). This video explains what Surface Plasmon Resonance technology is, how it is used to detect small molecules and their interaction with other proteins.For more 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. Localized surface plasmon resonance (LSPR) has emerged as a leader among label-free biosensing techniques in that it offers sensitive, robust, and facile detection. Traditional LSPR-based biosensing utilizes the sensitivity of the plasmon frequency to changes in local index of refraction at the nanoparticle surface.

A localized surface plasmon is the result of the confinement of a surface plasmon in a nanoparticle of size comparable to or smaller than the wavelength of light used to excite the plasmon. When a small spherical metallic nanoparticle is irradiated by light, the oscillating electric field causes the conduction electrons to oscillate coherently. When the electron cloud is displaced relative to its original position, a restoring force arises from Coulombic attraction between electrons and nuclei.

2011-11-07 Localized surface plasmon resonance (LSPR) is shown to be effective in trapping light for enhanced light absorption and hence performance in photonic and optoelectronic devices.
