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 thehighest concentration (3 mg/mL) at all time points.Keywords: nanotechnology, drug delivery, bactericide, magnetic nanoparticles Nhiem TranAparna MirDhriti Malliket alDove Medical PressarticleMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol 2010, Iss default, Pp 277-283 (2010)
