Copper-silver ferrite nanoparticles synthesized by a simple and rapid solution combustionmethod using glycine as complexing agent. Cu-Ag nanoparticles were and characterizedby X-ray diffraction and scanning electron microscopy. In vitro assays were established asa means of evaluating the potential of interaction and mean inhibition rates on severalstrains using the diffusion method in liquid broth medium. Ultraviolet-visible spectroscopyanalyses were applied for comparing relative amounts of strains eliminated or inhibitedthrough physical sample mechanisms. Results indicated that the amount of silver ions inthe copper ferrites influences the crystal microstructure and antibacterial properties of thecopper ferrites.
