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 (e.g., epoxy groups) allows for easy conjugation with biomolecules, making them suitable for bioseparation (such as DNA, proteins, or cells), enzyme immobilization, diagnostic applications, and biosensors for rapid and accurate detection of specific analytes.

Also employed as catalyst supports in chemical processes, where catalysts are anchored on the surface for easy magnetic separation and reuse.

Additionally used in environmental remediation for selective adsorption and removal of heavy metal ions or organic pollutants from water. The porous nature and high surface area enhance loading capacity, while the monodispersity ensures consistent performance in microfluidic and lab-on-a-chip technologies.
