"Surface plasmon resonance" is the resonant oscillation of conduction electrons at the interface between a negative and positive permittivity material stim
Surface plasmon resonance is used by biochemists to study the mechanisms and kinetics of ligands binding to receptors (i.e. a substrate binding to an enzyme). Multi-parametric surface plasmon resonance can be used not only to measure molecular interactions but also nanolayer properties or structural changes in the adsorbed molecules, polymer layers or graphene, for instance. Localized surface-plasmon resonance (LSPR) refers to the collective oscillation of electrons at the interface of metallic structures, which could be produced through the electron-magnetic interaction of the metal with incident light of a specific wavelength (Haes and Van Duyne, 2002; McFarland and Van Duyne, 2003; Hutter and Fendler, 2004). The plasmon resonant frequency is highly sensitive to the refractive index of the environment; a change in refractive index results in a shift in the resonant frequency. As the resonant frequency is easy to measure, this allows LSP nanoparticles to be used for nanoscale sensing applications.

DOI: 10.1103/PhysRevE.73.036609 PACS number s : … 2012-07-19 2015-06-01 For the case of localized surface plasmons, light interacts with particles much smaller than the incident wavelength (Figure 1b). This leads to a plasmon that os-cillates locally around the nanoparticle with a frequency known as the LSPR (41, 43). Similar to the SPR, the LSPR is sensitive to changes in the local dielectric environment (43, 45, 46). Here we present our experimental results in synthesizing Au-Ag bimetallic nanoalloys with tunable localized surface plasmon resonance frequency through nanosecond laser-induced heating in the presence of polyvinyl alcohol as a reducing and capping agent via three different procedures: (i) Mixture of HAuCl 4 and AgNO 3 precursors, (ii) Mixture of Au nanoparticles (NPs) and AgNO 3 precursor and … 2017-04-20 Surface Plasmon Resonance in a Thin Metal Film 1 Background In this experiment you will observe and record the surface plasmon resonance (SPR) curve for a thin metal film. This is done by shining monochromatic light through a glass prism, onto the film, and recording the intensity of the reflected light vs. angle of incidence (see Fig. 3).
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 …

The integration of silver and gold nanoparticles with graphene is frequently sought for the realization of hybrid materials with superior optical, photoelectric and photocatalytic performances. A crucial aspect for these applications is how the surface plasmon resonance of metal nanoparticles is modified aft 2016 most accessed PCCP articles
Surface plasmon resonance (SPR) 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 (typically gold or silver) surfaces or onto the surface of metal nanoparticles . Surface plasmon resonance refers to the electromagnetic response that occurs when plasmons are oscillating with the same frequency on the surface of a material. As these plasmons oscillate at specific resonant frequencies, they move with periodic driving forces that can become large amplitude oscillations when they interact.
