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. Commonly applied in cancer therapy for site-specific treatment, reducing systemic toxicity. Also employed in bioseparation processes to isolate cells, proteins, or nucleic acids efficiently. Their porous nature supports high loading capacity, while the monodisperse characteristic ensures consistent performance in diagnostic and therapeutic applications.
