dc.description.abstract | The paper reports a new route for the fabrication and determination of physicochemical properties and
biological activity, of metallic silica-based nanostructure (Ag/SiO2, Cu/SiO2). A research studies shows
mono-dispersed nanoparticles in silica matrix with an average size of 12 nm for silver, as well as 12 nm
and 4 nm, respectively for copper in hydrophobic and hydrophilic silica composites. The chemical
analysis highlights metallic silver and copper ions heterogeneously distributed in the composite as well
as metallic oxides such as Ag2O, Cu2O and CuO in hydrophobic system, and CuO in hydrophilic one.
Structural research evidences the presence of amorphous, stoichiometric and non-stoichiometric
crystalline phase of silica. Biological studies reveal potentially inhibition of growth gram-positive and
gram-negative bacteria as well as microscopic fungi. The size of metal nanoparticles and level of silica
hydrophobicity show the highest inhibition bacterial growth for hydrophilic system with embedding
inside them, 4 nm in size copper nanoparticles. Finally, cytotoxic interaction against human cells with
respect to silver and copper silica-based nanocomposites was not found. | pl_PL |
