Functionalization of surgical meshes with antibacterial hybrid Ag@crown nanoparticles

We report here on functionalization of surgical meshes (PVDF) with novel hybrid material, consisting of Ag@crown nanoparticles, embedded on CaCO3/PEG nanosheets. Nanosheets of PEG 4000 with average thickness of 25 nm enclosing CaCO3 nanoparticles with average sizes of 150 nm were applied for sustained release of Ag@crown nanoparticles that in turn serve as antibacterial agent. The characterization of obtained hybrid nanostructures was carried out by microscopic and spectroscopic methods. Microbiological tests confirmed the effectiveness of hybrid material, consisting of Ag@crown nanoparticles, embedded in CaCO3/PEG nanostructure, as an antibacterial coating for surgical meshes. This coating was applied to insure antibacterial properties of meshes against microorganism colonization, in order to significantly improve their action in typical applications.
