Abstract
Transition metals of copper zinc manganese and nickel were substituted into cobalt ferrite nanoparticles via a sol–gel route using citric acid as a chelating agent The microstructure and elemental compositions of the nanoparticles were characterized using scanning electron microscopy combined with energy dispersive Xray spectroscopy The particle size of the nanoparticles was investigated using particle size analyzer and the zeta potentials were measured using zeta potential analyzer The phase components of the synthesized transition metalsubstituted cobalt ferrite nanoparticles were studied using Raman spectroscopy The biocompatibility of the nanoparticles was assessed using osteoblastlike cells Results indicated that the substitution of transition metals strongly influences the physical chemical properties and biocompatibility of the cobalt ferrite nanoparticles
