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 conjugation with biomolecules, making them suitable for bioseparation, enzyme immobilization, and diagnostic applications.

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

Also utilized in controlled release agriculture systems, where they deliver nutrients or pesticides in a sustained manner.

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

Additionally, they serve as reusable catalyst supports, easily separable from reactions via magnetic fields, and enhance sensitivity in biosensors due to their small surface area and magnetic properties.
