In this work we present the mechanochemical synthesis of nanoparticles (NPs) of and NiFe2O4, with average diameters of 7 ± 1.5 and 5 ± 1.5 nm, respectively. NPs were characterized by powder X-ray diffraction (XRD) and transmission electron microscopy (TEM). The bacterial susceptibility of the P. aeruginosa and S. aureus strains, against the NPs obtained, was evaluated by a Trypticasein Agar Soy Broth (TSB) test. The synthesis method described in this work provides a viable, easy and friendly to the environment, for the production of nanomaterials. It also has some advantages such as short reaction times, high performance and low cost, for obtaining materials formed by nanostructured oxides with properties particular physicochemicals, which can be applied as antimicrobial agents on contact surfaces.
