Bactericidal effect of iron oxide nanoparticles on Staphylococcus aureus.

Tran N, Mir A, Mallik D, Sinha A, Nayar S, Webster TJ - Int J Nanomedicine (2010)

Bottom Line: In order to study the effects of iron oxide (IO) nanoparticles on Staphylococcus aureus, IO nanoparticles were synthesized via a novel matrix-mediated method using polyvinyl alcohol (PVA).Further, S. aureus were grown in the presence of three different IO nanoparticle concentrations for four, 12, and 24 hours.Live/dead assays were performed and the results provide evidence that IO/PVA nanoparticles inhibited S. aureus growth at the highest concentration (3 mg/mL) at all time points.

ABSTRACT
In order to study the effects of iron oxide (IO) nanoparticles on Staphylococcus aureus, IO nanoparticles were synthesized via a novel matrix-mediated method using polyvinyl alcohol (PVA). The IO nanoparticles were characterized by transmission electron microscopy and dynamic light scattering. Further, S. aureus were grown in the presence of three different IO nanoparticle concentrations for four, 12, and 24 hours. Live/dead assays were performed and the results provide evidence that IO/PVA nanoparticles inhibited S. aureus growth at the highest concentration (3 mg/mL) at all time points.

f5-ijn-5-277: X-ray diffraction results of synthesized nanoparticles confirmed the existence of magnetite (Fe3O4) and maghemite γ-Fe2O3.

Mentions: The XRD pattern confirmed that the final product was a mixture of Fe3O4 and γ-Fe2O3 (Figure 5). The existence of γ-Fe2O3 was common and was because of the oxidation of Fe3O4 during synthesis.26
