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 biomolecules, making them suitable for bioseparation (e.g., DNA, proteins, cells), enzyme immobilization, and diagnostic applications.

Commonly applied in wastewater treatment for efficient removal of heavy metals and organic pollutants through adsorption and magnetic recovery.

Utilized as magnetic supports in catalysis systems, facilitating easy separation and reuse of catalysts.

Employed in controlled release agriculture systems, where they deliver nutrients or pesticides in a sustained and site-specific manner.

Have potential in medical imaging, such as MRI, due to magnetic properties enhancing image contrast.

Their monodispersity ensures consistent performance in microfluidic devices and as calibration standards in analytical instruments.
