    摘要: The present invention discloses a magnetic nanocomposite for inhibiting/treating cancer and a method for fabricating the same. The magnetic nanocomposite comprises a core formed of a plurality of magnetic nanoparticles made of ferric ferrous oxide (Fe3O4); a shell made of a carboxy-functionalized polyaniline; and an anti-tumor medicine bound to the external surface of the shell. The method of the present invention fast fabricates the magnetic nanocomposite in a simple way. The medicine of the present invention has a longer half life and a better thermal stability. The present invention disperses the water-insoluble medicine in water uniformly to decrease the biological rejection. Moreover, the magnetic nanocomposite of the present invention is guided to the nidus by an external magnetic field to increase the local concentration of the medicine and provide an effective chemotherapy. Therefore, the present invention has competitive advantage over the conventional BCNU.

    摘要: Disclosed herein is a method for treating a brain disease in which focused ultrasound and magnetic targeting are applied to a subject in need of such treatment, so that therapeutic agent-magnetic nanoparticle composites are directed across the blood-brain barrier to a designated locus inside the brain of the subject. Each of the composites includes a magnetic nanoparticle that is formed of an iron-based core and a shell encapsulating the iron-based core, and a therapeutic agent that is bound to the shell of the magnetic nanoparticle. The magnetic nanoparticle has a size ranging from 5 to 200 nm. The iron-based core has a crystalline structure that imparts the composites with a sufficiently high magnetization, thereby enhancing magnetic targeting of the composites to the designated locus inside the brain of the subject. The magnetic targeting treatment is conducted via a magnet providing a magnetic flux density not less than 0.18 T.
