Presents the introductory welcome message from the conference General Chairs to the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Hybrid structures combing silver nanoparticles and few-layer graphene have been synthetized by combining low-energy ion beam synthesis and stencil techniques. A single plane of metallic nanoparticles plays the role of an embedded plasmonic enhancer located in dedicated areas at a controlled nanometer distance from deposited graphene layers....
The effect of an amorphous silica matrix on the structure and charge distribution of silver nanoparticles is investigated by dispersion-corrected DFT calculations. A matrix-induced electron loss of silver nanoparticles is reported.

Elaboration in a controlled way of large-area and efficient plasmonic substrates is achieved by combining sputtering of silver nanoparticles (AgNPs) and plasma polymerization of the embedding dielectric matrix in an axially asymmetric, capacitively coupled RF discharge maintained at low gas pressure. The plasma parameters and deposition...
Driven by many applications, the development of new biomaterials has considerably increased in the last decade. The current research strategies also involve revealing of the relationship between protein structure and function due to the exposure and interaction of proteins with non-biological organic and inorganic solid surfaces. Aiming at...
Silver nanoparticles (AgNPs) are widely used in the health-care sector and industrial applications because of their outstanding antibacterial activity. This bactericidal effect is mainly attributed to the release of Ag+ ions in an aqueous medium, the first step of which is the dissolution of the AgNP via the oxidation of its surface by O2. With...
A predictive modelling of plasmonic substrates appropriate to read ellipsometric spectra is presented in this work. We focus on plasmonic substrates containing a single layer of silver nanoparticles (AgNPs) embedded in silica matrices. The model uses the Abeles matrix formalism and is based on the quasistatic approximation of the classical...
