Modified Au-Based Nanomaterials Studied by Surface

Using layer potential techniques associated with the full Maxwell equations, we derive small-volume expansions for the electromagnetic fields, which are uniformly valid with respect to the nanoparticle’s bulk electron relaxation rate. Signal enhancement by gold nanoparticles is caused by several effects such as surface mass increase due to enhanced surface area, larger refractive index changes by the particle mass, themselves, and electromagnetic field coupling between the plasmonic properties of the particles (localized surface plasmon resonance) and propagating plasmons. 2007-09-17 · Plasmon resonance-based optical trapping of single and multiple Au nanoparticles.

Plasmons are quantum of plasma oscillation, i.e., it is the minimum amount of any particle, with the physical property involved in the interaction of a rapid oscillation in an electron density. Plasmon Resonance. Just as optical oscillation or light consists of photons, plasma oscillation consists of plasmons. Drude Model Plasmonic nanoparticles are particles whose electron density can couple with electromagnetic radiation of wavelengths that are far larger than the particle due to the nature of the dielectric-metal interface between the medium and the particles: unlike in a pure metal where there is a maximum limit on what size wavelength can be effectively coupled based on the material size.

Article Google Scholar Solutions of spherical gold nanoparticles are ruby red in color due to the strong scattering and absorption in the green region of the spectrum. Solutions of silver nanoparticles are yellow due to the plasmon resonance in the blue region of the spectrum (red and green light is unaffected). Localized surface plasmons have been observed since the Romans who used gold and silver nanoparticles to create colored glass objects such as the Lycurgus Cup (4th Century A.D.). A gold sol in the British museum, created by Michael Faraday in 1857, is still exhibiting its red color due to the plasmon resonance at ,530 nm [L.
