Synthesis and characterization of zinc/iron oxide composite nanoparticles and their antibacterial properties

▶ Zn/Fe oxide composite nanoparticles were synthesized by growth of Zn/Fe oxide films on gelatin/Zn/Fe oxide nuclei. ▶ The [Zn]/[Fe] ratios within the particle affected particle diameter and magnetic properties. ▶ Colloidal stability was achieved while maintaining adequate antibacterial activity.
