ABSTRACT

Cobalt ferrite nanoparticles (CoFe₂O₄ NPs) have emerged as versatile materials with a wide range of applications due to their unique physical and chemical properties. Their high coercivity, chemical stability, and tunable magnetic and electrical characteristics make them suitable for use in diverse fields, including biomedicine, environmental remediation, catalysis, and magnetic data storage. In the biomedical sector, cobalt ferrite nanoparticles are used for magnetic hyperthermia treatment and drug delivery systems, as well as in MRI as contrast agents due to their strong magnetic properties. Additionally, their application in environmental remediation has proven effective, particularly in the removal of heavy metals and organic contaminants from water. Their magnetic properties facilitate easy recovery and regeneration, making them a cost-effective option for water treatment processes. In the field of catalysis, cobalt ferrite nanoparticles are valuable due to their large surface area and electronic configuration, enhancing their efficiency in oxidation and reduction reactions. This makes them highly useful for industrial processes. Moreover, their high coercivity and magnetic anisotropy have found applications in magnetic data storage, where they offer the potential for increased data density and stability. However, despite their advantages, several challenges limit the full utilization of cobalt ferrite nanoparticles. Issues such as biocompatibility, synthesis feasibility at an industrial scale, and long-term stability in varying environmental conditions must be addressed. Future research is needed to overcome these challenges, with a particular focus on improving synthesis techniques for biomedical applications and employing green chemistry approaches for large-scale production. Additionally, studies on enhancing their stability in diverse environmental conditions will further increase their industrial and environmental applications. With continued research, cobalt ferrite nanoparticles are poised to offer new solutions across a variety of sectors, making them one of the most promising materials in nanotechnology.
