Abstract: Magnetic nanoparticles (MNPs) possess unique properties which can be applied in nanomedicine: they address targets such as cellular therapy, tissue repair, nanobiosensors, drug delivery, magnetic resonance imaging and magnetic fluid hyperthermia. In the last decades, much research has been devoted to the synthesis of magnetic nanoparticles. Especially during the last few years, many publications have described efficient synthetic routes to shape-controlled, highly stable, and monodisperse magnetic nanoparticles. Most studies suggested that the cobalt ferrites could be a promising materials for various applications. In this work, different sized cobalt ferrite nanoparticls (CFNP) were selectively synthesized with narrow size distribution, by using chemical precipitation methods. The obtained powder was calcined at different temperature (600 °C, 800 °C, 900 °C ,1000 °C). Different characterization like Transmission Electron Microscope (TEM ) was done to visualize the morphology and particle size, X-ray Diffraction (XRD) analysis was done to know the phases present, Vibrating Sample Magnetometer (VSM) to get the magnetization and coercivity of the powder, Ultraviolet - Visible Spectroscopy (UV-VIS) and Fourier Transform Infrared Spectroscopy (FTIR) analysis further confirmed the presence of cobalt ferrite nanoparticles. All of the characterization methods confirmed the formation of single-phase CFNP in the range 10–115 nm depending on the annealing temperature.
