Curvature of the Localized Surface Plasmon Resonance Peak
Analytical Chemistry, 2014Localized surface plasmon resonance (LSPR) occurring in noble metal nanoparticles (e.g., Au) is a widely used phenomenon to report molecular interactions. Traditional LSPR sensors typically monitor shifts in the peak position or extinction in response to local refractive index changes in the close vicinity of the nanoparticle surface.

Localized surface plasmon resonances of a metal nanoring
Physical Chemistry Chemical Physics, 2020Using the linear combination of atomic orbitals real-time-propagation rt-TDDFT technique and transition contribution maps, we study the optical and plasmonic features of a metal nanoring made up of sodium atoms.

Localized Surface Plasmon Resonance Spectroscopy and Sensing
Annual Review of Physical Chemistry, 2007Localized surface plasmon resonance (LSPR) spectroscopy of metallic nanoparticles is a powerful technique for chemical and biological sensing experiments. Moreover, the LSPR is responsible for the electromagnetic-field enhancement that leads to surface-enhanced Raman scattering (SERS) and other surface-enhanced spectroscopic processes.

Exploitation of Localized Surface Plasmon Resonance
Advanced Materials, 2004AbstractRecent advances in the exploitation of localized surface plasmons (charge density oscillations confined to metallic nanoparticles and nanostructures) in nanoscale optics and photonics, as well as in the construction of sensors and biosensors, are reviewed here.

Localized Surface Plasmon Resonance Spectroscopy near Molecular Resonances
Journal of the American Chemical Society, 2006The peak location of the localized surface plasmon resonance (LSPR) of noble metal nanoparticles is highly dependent upon the refractive index of the nanoparticles' surrounding environment. In this study, new phenomena are revealed by exploring the influence of interacting molecular resonances and nanoparticle resonances.

Surface-Dependent Localized Surface Plasmon Resonances in CuS Nanodisks
ACS Applied Materials & Interfaces, 2013We demonstrated revertible shifts of surface-dependent localized surface plasmon resonances (LSPRs) in CuS nanodisks. Oleylamine (OYA) served as a solvent and surface ligand covering on CuS nanodisks during the thermolysis of single-source precursor copper ethylxanthate (Cu(ex)2).

A single molecule immunoassay by localized surface plasmon resonance
Nanotechnology, 2010Noble metal nanoparticles exhibit sharp spectral extinction peaks at visible and near-infrared frequencies due to the resonant excitation of their free electrons, termed localized surface plasmon resonance (LSPR). Since the resonant frequency is dependent on the refractive index of the nanoparticle surroundings, LSPR can be the basis for sensing ...

Localized surface plasmon resonance in refractory metamaterials
Advanced Fabrication Technologies for Micro/Nano Optics and Photonics XIV, 2021Owing to their tunable electromagnetic properties, subwavelength structures such as metamaterials have enabled novel applications across fields of engineering. In particular, metal-insulator-metal (MIM) plasmonic metamaterials have demonstrated efficient light energy absorption based on localized surface plasmon resonances. Due to these properties, MIM

Sensitivity and Optimization of Localized Surface Plasmon Resonance Transducers
ACS Nano, 2011Gold nanoisland films displaying localized surface plasmon resonance optical response were constructed by evaporation on glass and annealing. The surface plasmon distance sensitivity and refractive index sensitivity (RIS) for island films of different nominal thicknesses and morphologies were investigated using layer-by-layer polyelectrolyte multilayer

Resonant-enhanced localized surface plasmon resonance spectroscopy
SPIE Proceedings, 2006The extinction maximum of the localized surface plasmon resonance (LSPR) of noble metal nanoparticles is highly dependent upon the refractive index of the nanoparticles' surrounding environment. In this study, the effect that molecular resonances have on the intensity, LSPR peak width, and LSPR shift of the LSPR of Ag nanoparticles is monitored ...
