Surface plasmon resonance of gold nanoparticles assemblies at liquid | liquid interfaces In the case of gold nanorod the plasmon resonance splits into two modes: one longitudinal mode parallel to the long axis of the rod and a transverse mode perpendicular to the first. In this work we use photoacoustic (PA) technique to study the shape dependence of surface plasmon resonance of gold nanoparticles (dots and rods) in addition to their dependence on the aspect ratio in the case of The presence of longitudinal surface plasmon resonance (LSPR) provides GNRs with richer optical properties, which lead to local field, Raman, and fluorescence enhancement.

R. China Local surface plasmon resonance of gold nanoparticles as a correlative light and electron microscopy (CLEM) tag for biological samples In this study, we investigated use of local surface plasmon resonance (LSPR) of metal nanoparticles (NPs) as a correlative light and electron microscopy (CLEM) tag for biological samples. This structural control provides a method for systematically shifting the surface plasmon resonance (SPR) of the particles, based on the decrease in dipolar coupling with increased interparticle distance. Through choice of dendrimer generation, we were able to tune interparticle spacing over a 2.1 nm range, resulting in an 84 nm shift in the SPR. LSPRs (localized surface plasmon resonances) are collective electron charge oscillations in metallic nanoparticles that are excited by light. They exhibit enhanced near-field amplitude at the resonance wavelength. 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 after assembly with graphene.
