Antibacterial and Cytotoxic Study of Hybrid Films Based on Polypropylene and NiO or NiFeO Nanoparticles.

This study presents an in vitro analysis of the bactericidal and cytotoxic properties of hybrid films containing nickel oxide (NiO) and nickel ferrite (NiFeO) nanoparticles embedded in polypropylene (PP). The solvent casting method was used to synthesize films of PP, PP@NiO, and PP@NiFeO, which were characterized by different spectroscopic and microscopic techniques. The X-ray diffraction (XRD) patterns confirmed that the small crystallite sizes of NiO and NiFeO NPs were maintained even after they were incorporated into the PP matrix.
