Journal ArticleDOI
Optical properties of gold nanorings
Javier Aizpurua,Per Hanarp,Duncan S. Sutherland,Mikael Käll,Garnett W. Bryant,F. J. García de Abajo +5 more
TL;DR: The optical response of ring-shaped gold nanoparticles prepared by colloidal lithography is investigated and the electric field associated with these plasmons exhibits uniform enhancement and polarization in the ring cavity, suggesting applications in near-infrared surface-enhanced spectroscopy and sensing.
Journal ArticleDOI
Optical Properties of Short Range Ordered Arrays of Nanometer Gold Disks Prepared by Colloidal Lithography
TL;DR: In this article, the optical properties of gold nanodisk arrays prepared by colloidal lithography were studied experimentally and it was found that more oblate disk shapes have higher sensitivity.
Journal ArticleDOI
Control of nanoparticle film structure for colloidal lithography
TL;DR: In this article, a method to control the deposition of polystyrene particles on flat oxidised titanium surfaces for particle sizes between 20 and 500 nm and coverages of 0.45 are demonstrated and discussed.
Journal ArticleDOI
Optical Spectroscopy of Nanometric Holes in Thin Gold Films
TL;DR: In this article, isolated nanometric holes in optically thin Au films exhibit a localized surface plasmon resonance in the red to near-infrared region, analogous to a dipolar particle plasmoron.
Journal ArticleDOI
Protein Adsorption on Model Surfaces with Controlled Nanotopography and Chemistry
Frédéric A. Denis,Per Hanarp,Duncan S. Sutherland,Julie Gold,Christian Mustin,Paul Rouxhet,Yves F. Dufrêne +6 more
TL;DR: In this article, the authors evaluated the influence of substrate surface characteristics on protein adsorption processes and concluded that the supramolecular organization of the adsorbed layer is controlled both by surface chemistry and topography.
