“…They play a major role in biotechnology, e.g. DNA scanning (Vo-Dinh et al, 1999;Dubertret et al, 2001;Bauer et al, 1999;Taton et al, 2000), in solar cells (Westphalen et al, 2000;Stenzel et al, 1995), anti-counterfeiting (Bauer et al, 2003) and optical data storage (Ditlbacher et al, 2000). These areas of research and applied science exploit the so-called 'plasmon resonance' of the noble metal nanoparticles.…”

Pattern formation is investigated in a one-dimensional gradient prepared from an aqueous colloidal gold nanoparticle solution. The hydrodynamic process can be reconstructed by determining the prominent length scales and surface roughness in the dried gradient. The structural information is obtained using a combination of grazing-incidence small-angle X-ray scattering, which is a method of high-statistical relevance, and a moderate microfocused beam. This allows for scanning the gradient and to locally reveal the structure of the thin film. Our results, based on a simplified hydrodynamic model, indicate a system oscillating between depleted regions, nanoparticle domains and complete nanoparticle layers.

“…Surface plasmon resonance (SPR) biochemical sensors based on noble-metal nanoparticles is a particularly promising type of application [2][3][4][5][6]. Similar to the case of conventional SPR sensors with spectral interrogation [7], the sensing capability of metal nanoparticles is linked to the variation in optical response with near-field electrodynamic environment.…”

We model the optical response of surface plasmon resonance (SPR) sensors based on colloidal metal nanoparticles using extended Mie theory. The theoretical description includes the particle adsorption layer, the surrounding medium as well as particle-particle and particlesubstrate electromagnetic coupling effects. We obtain quantitative agreement with recently reported experimental results on gold nanoparticle SPR sensors, indicating the possibility to perform accurate a priori estimates of detector sensitivity for different particle sizes and compositions in a variety of electromagnetic environments. The possibility to increase sensitivity by using non-spherical silver particles as SPR sensors is discussed. #
