Abstract: (2589 Views)
Recently, metal oxide nanoparticles have been considered by researchers as antibacterial agentsbecause of the resistance of bacterial strains to organic antibacterials. Iron oxide and zinc oxide nanoparticles, while easy to synthesize and cost-effective, have high antibacterial properties against a variety of gram-positive and gram-negative bacteria. In this study, iron oxide and iron oxide-zinc oxide nanoparticles were synthesized by electric discharge method in liquid. For microstructural studies, XRD and UV_VISIBLE methods were used. The results indicate the formation of Fe3O4 and Fe phases in the iron oxide sample and ZnO and ZnFe2O4 in the iron-zinc oxide sample. The crystal sizes were 8 nm and 18.46 nm, respectively.
FE-SEM and TEM analyzes confirmed the spherical and uniform core-shell structure. Antibacterial analyzes were performed by two methods: minimum inhibitory concentration (MIC) and optical density, which confirmed the antibacterial properties of nanoparticles in both methods. Iron-oxide nanoparticles Zinc oxide performed better than iron oxide nanoparticles due to the activation of more mechanisms and the synergistic effects of the Fe2+,Fe3+ and Zn2+ cations.
