In this work, Fe3O4@Ag hybrid nanomaterials with core-shell structure were prepared by reducing Ag+ on the surface of Fe3O4 nanoparticles (NPs) using seeded - growth method in organic solvents. TEM images indicated the as-synthesized nanoparticles were spherical in shape and fairly uniform in size, with an average diameter of 15,8 nm. As a result, after being encapsulated by poly (maleic anhydride-alt-1-octadecen) (PMAO), the surface of Fe3O4@Ag becomes hydrophilic and well-dispersed in water. The hybridization of Ag NPs and Fe3O4 NPs showed more noticeable bactericidal activity than that of Ag-NPs. The antibacterial activity of Fe3O4-Ag hybrid nanomaterials showed potent inhibitory activity against both Gram-positive and Gram-negative pathogens.
