Monodispersed magnetite microspheres are widely used in biomedical applications due to their magnetic properties and uniform size. They are employed in magnetic resonance imaging (MRI) as contrast agents to enhance image clarity for better diagnosis. In drug delivery systems, these microspheres enable targeted therapy by guiding drugs to specific sites in the body using external magnetic fields, minimizing side effects. They are also utilized in cell separation and purification processes, where their magnetic nature allows for efficient isolation of specific cell types. Additionally, these microspheres play a role in environmental remediation, aiding in the removal of contaminants from water through magnetic separation techniques. Their uniformity and stability make them valuable in research and industrial applications requiring precise control and manipulation.
