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 over the release of therapeutic agents to specific areas in the body. In diagnostics, these microspheres are utilized in magnetic separation techniques to isolate and purify biomolecules such as DNA, RNA, and proteins. Additionally, they play a role in environmental remediation by adsorbing and removing heavy metals and pollutants from water. Their uniform size and magnetic responsiveness make them valuable in various research and industrial applications.
