Abstract

Magnetic spinel ferrite materials have attracted considerable attention due to their diverse applications in biomedical, water treatment, and industrial electronic devices. This mini review focuses on the synthesis and applications of spinel ferrites across various fields, with a particular emphasis on doped spinel ferrite nanoparticles. These doped nanoparticles exhibit remarkable electrical and magnetic properties, making them highly suitable for various applications. For instance, in the biomedical field, spinel ferrite nanoparticles have shown promising potential in targeted drug delivery systems, magnetic hyperthermia for cancer treatment, and contrast agents for Magnetic Resonance Imaging (MRI). In water treatment, these nanoparticles have been utilized for the removal of heavy metals, organic pollutants, and dyes due to their excellent adsorption properties.

Additionally, in the realm of industrial electronic devices, spinel ferrite nanoparticles have been employed in high-frequency transformers, Electromagnetic Interference (EMI) shielding, and power inductors, showcasing their versatility and relevance in modern technological applications. Additionally, by substituting metallic atoms, the physical properties of spinel ferrites can be tailored, leading to enhanced performance. The review examines the latest and most significant developments in the utilization of magnetic ferrite nanoparticles and provides insights on choosing the appropriate magnetic ferrites for specific applications.
