Monodispersed magnetite microspheres are widely used in biomedical applications, particularly in magnetic resonance imaging (MRI) as contrast agents to enhance image clarity. They are also employed in targeted drug delivery systems, where their magnetic properties allow precise control and localization of therapeutic agents to specific areas in the body. In diagnostics, these microspheres are utilized in magnetic separation techniques for isolating and purifying biomolecules such as DNA, RNA, and proteins. Additionally, they play a role in hyperthermia treatment for cancer, where they generate heat under an alternating magnetic field to destroy tumor cells. Their uniform size and magnetic responsiveness make them valuable in various research and industrial applications, including environmental remediation for the removal of pollutants from water.
