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.

  • Patent number: 8951567
    Abstract: Discrete microstructures of predefined size and shape are prepared using sol-gel phase-reversible hydrogel templates. An aqueous solution of hydrogel-forming material is covered onto a microfabricated silicon wafer master template having predefined microfeatures, such as pillars. A hydrogel template is formed, usually by lowering the temperature, and the formed hydrogel template is peeled away from the silicon master template. The wells of predefined size and shape on the hydrogel template are filled with a solution or a paste of a water-insoluble polymer, and the solvent is removed to form solid structures. The formed microstructures are released from the hydrogel template by simply melting the hydrogel template in water. The microstructures are collected by centrifugation. The microstructures fabricated by this method exhibit pre-defined size and shape that exactly correspond to the microwells of the hydrogel template.

  • Patent number: 8945629
    Abstract: The invention is a nanoparticle that contains an anticancer drug that is released in cancer cells when administered to a subject. The nanoparticles have a core including the anticancer drug and polymer chains that are soluble at the pH of the cancer cell. The core is surrounded by a layer of polymer chains that are insoluble at the pH of healthy tissue but soluble at the pH of the cancer interstitium. An outside layer is made of water-soluble polymer chains to shield the nanoparticle from RES recognition and give the nanoparticle a long circulation time in the bloodstream of the subject. The outside layer may also include folic acid moieties that bind folic acid receptors on the surface of the cancer cell.

  • Patent number: 8940336
    Abstract: The invention provides polymer particles that are obtainable by a method selected from emulsion methods, diffusion methods and evaporation methods carried out in the presence of surface-engineering surfactant which is one or more polymer that displays a lower critical solution temperature, in aqueous media, that is between 10 to 90° C., this polymer being the polymerization product of one or more monomer selected from polymerisable alkyleneglycol acrylate monomers and polymerisable alkyleneglycol methacrylate monomers. The polymer particles can be used in controlled release applications, such as flavour release applications, fragrance release applications and biomedical applications. The invention also provides a cell support matrix comprising the polymer particles.
