  • Publication number: 20120095325
    Abstract: 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.

  • Publication number: 20110101282
    Abstract: The present invention provides a water-soluble self-acid-doped polyaniline blends, comprising a 70-90% weight percentage polyaniline derivative and 10-30% weight percentage at least a water-soluble polymer. The blend can be used to produce a conductive polymer film and/or a conductive-polymer composite film. In the present invention, a water-soluble self-acid-doped polyaniline derivative is blended with a water-soluble polymer to enhance the mechanical properties and the coating-to-substrate adhesion of the electric conductive polymer film or the electric conductive-polymer composite film, and increase the conductivity of the blender. In addition, the blend containing a water-soluble self-acid-doped polyaniline of the present invention is biotoxicity-free and has free radical-capture capability. Thus it can be used as a biocompatible and conductive biomedical material.

  • Publication number: 20110104294
    Abstract: 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.

  • Patent number: 6586876
    Abstract: The present invention relates to an organic light-emitting device which provides an electroluminescence (EL) or photoluminescence (PL) device with high external quantum efficiency. The present invention forms a composite film layer with continuously changing refraction indices between an ITO transparent electrode and a substrate made of plastic or glass. The refraction index of the composite film layer is the same as the ITO electrode at the interface with the ITO electrode. It decreases along the direction perpendicular to the substrate in a linear or nonlinear way. The refraction index is the same as that of the plastic or glass at the interface with the substrate. This way can avoid reflection due to the difference in the refraction index across the interface. The excited light originally trapped in the ITO electrode can be guided outwards.

  • Patent number: 6566805
    Abstract: A flexible organic electro-luminescent device is provided, in which a titanium dioxide-silicon dioxide composite layer is formed on the upper and lower surfaces of a transparent plastic substrate. A transparent conductive electrode and an organic luminescent layer are formed in sequence on one of surfaces of the composite layer. The organic luminescent layer is either small molecule luminescent material or polymer luminescent material. Then, a metal electrode is formed on the organic luminescent layer, and a silicon dioxide protecting layer is formed on the metal electrode to enclose the metal electrode and the organic luminescent layer completely. The titanium dioxide-silicon dioxide composite layer and silicon dioxide protecting layer are formed by ion-assisted electron gun evaporation in the temperature lower than 100° C., which does not result in the thermal loading to the small molecule and polymer organic electro-luminescent device.

  • Patent number: 6383629
    Abstract: An optical element having a water repellant composite layer composed of CaF2 and TiO2. The optical element includes a substrate and a composite layer having a chemical formula (100-X)CaF2—(X)TiO2 formed over the substrate. The X in the chemical formula represents the molar percentage of TiO2 in the composite layer. Through the addition of TiO2 into a CaF2 layer to form the composite layer, surface roughness, adhesion strength and hardness of the layer in the optical element is improved without compromising water resistant capacity. For a composite layer having a percentage composition of TiO2 between 2% to 100%, contact angle of water droplets is always greater than 100° comparable with Teflon. The refractive index varies according to the composition, but in general, the refractive index falls between 1.23 (2%TiO2) to 2.3 (pure TiO2) for incoming light with a wavelength of 600 nm.

  • Patent number: 5571454
    Abstract: This invention relates to homogeneously doped conductive polymer and a polymer blend thereof, wherein the dopant is a protonic acid having long carbon chain or larger substituent group. The resulting doped conductive polymer solution and polymer blend solution thereof can be cast to form free-standing films with metallic luster, of which the conductivities remain stable in the ambient condition and are in the range of 10.sup.-6 to 10.sup.-1 S/cm. The conductive polymer film and the conductive polymer composite film so prepared can be utilized in the anti-static wrapping materials for electronic components, and in electromagnetic interference shielding.
