Novel strategy for f-HAp/PVP/Ag nanocomposite synthesis from fluoro based ionic liquid assistance: Systematic investigations on its antibacterial and cytotoxicity behaviors.
A novel biomimetic f-HAp/PVP/Ag nanocomposite was synthesized under the ionic liquid medium, which was composed of inorganic and organic nanofillers like fluor-hydroxyapatite, silver nanoparticles and polyvinyl pyrrolidone. In composite synthesis, the first time we were used fluorine based ionic liquid for the fluorine contents on the fluor-hydroxyapatite nanoparticles which were resulting in very good crosslinking and interfacial bonding with the PVP and Ag nanoparticles. Ionic liquid has assisted good morphological structure of both inorganic materials. The chemical interaction and crystallinity changes of the nanocomposite were evaluated by FTIR and XRD studies. The surface morphology and composition of the samples were observed by FE-SEM, HR-TEM and EDS analyses. This report reveals that the greener approach for synthesis of fluor-hydroxyapatite nanocomposite and sustained delivery of silver and fluorine ions from the fluor-hydroxyapatite surface to the bacterial surface have been reducing the bacterial growth rate which was evaluated by different pathogenic bacterial strains via different methods and it also favourable cytotoxicity effect with human osteosarcoma (MG-63) cells.
