Used in targeted drug delivery systems due to their uniform size and magnetic responsiveness, enabling precise control and release of therapeutic agents under external magnetic fields. Their surface-functionalized structure allows for easy attachment of drugs, antibodies, or imaging agents, making them suitable for biomedical applications such as cancer therapy and magnetic resonance imaging (MRI) contrast enhancement. Also employed in environmental remediation for the removal of heavy metals and organic pollutants from wastewater, where the microspheres can be magnetically separated after adsorption. Their high surface area and monodisperse nature improve efficiency and reproducibility in diagnostic assays and separation technologies.
