“…This is a useful analytical tool in bioengineering for determining the chemical state of specific functional groups in the uppermost 10 nm of a surface coating [19]. The presence of silver in the surface coating was confirmed by the presence of the peak at 368.2 eV indicative of Ag 0 , • most likely in a nanoparticle form (Fig.…”

“…Previous studies have shown that when silver salts are incorporated into sol-gel coatings a high initial release of silver ions is followed by a more gradual and sustained release profile [19]. Ion release from such biomaterials is governed by (a) the amount of available surface metal, (b) the area of the exposed coating, (c) the degree of hydrophobicity of the coating inter-face, and (d) the volume of the contact fluid [23].…”

“…Several chemical methods for manufacturing antibacterial silver release coatings have been reported such as silver doped sol-gels and silver doped fluoropolymers. These coatings independently showed antibacterial activity but inorganic and organic contamination was still observed after bacterial exposure [19,26]. In this work, biocidal silver ions and hydrophobic hybrid sol-gel coatings were combined to develop a dual-action hygienic coating for protection of surfaces against the precipitation of crystalline deposits and S. epidermidis colonisation.…”
