TL;DR: Electrodynamic simulations of gold nanoparticle spectra were used to investigate the sensitivity of localized surface plasmon band position to the refractive index, n, of the medium for nanoparticles of various shapes and nanoshells of various structures, and the results extended to particles of other shapes, composed of other metals, and to higher-order modes.

TL;DR: In this article, the authors examined the electrodynamics of silver nanoparticles and of clusters of nanoparticles, with an emphasis on extinction spectra and of electric fields near the particle surfaces that are important in determining surfaceenhanced Raman (SER) intensities.

TL;DR: In this paper, the authors examined the effect of solvent on the optical extinction spectrum of periodic arrays of surface-confined silver nanoparticles fabricated by nanosphere lithography (NSL) and showed that the defect sites that occur as a byproduct of the NSL fabrication process play a negligible role in the macroscale extinction spectrum.

TL;DR: In this paper, the structural basis for the aggregation-induced optical properties of colloidal gold nanosphere aggregates is examined by means of electrodynamics calculations, using accurate nanoparticle polarizabilities determined from Mie theory, an iterative conjugate-gradient solution algorithm, and fast Fourier transform methods for efficient solution of the electrodynamic interacting nanoparticle equations.

TL;DR: DNA hybridization enables the three-dimensional assembly of Au nanoparticles and streptavidin andStructural and melting investigations on the assemblies showed their formation was reversible.
