  • Patent number: 8246868
    Abstract: A W/O emulsion is produced from an aqueous solution containing a substance to be entrapped in a vesicle in a dissolved or suspended state and an oil phase containing an emulsifier; subsequently, the W/O emulsion is cooled to a temperature at which the aqueous solution of the W/O emulsion becomes a frozen particle and the oil phase maintains a liquid state, and the oil phase is removed; thereafter, an oil phase containing a vesicle constituent lipid is added to the frozen particle, and the obtained mixture is then stirred, so as to substitute the emulsifier on the surface of the frozen particle with the vesicle constituent lipid; and thereafter, an external Water phase is added to the frozen particle coated with a lipid membrane, so as to hydrate the lipid membrane by the external water phase. This process achieves a high entrapment yield of a desired substance while controlling desired physical properties such as particle diameter.

    Abstract: A niosome having a metalloporphyrin complex embedded therein comprising a cationized metalloporphyrin complex and a niosome-forming substance. The niosome having a metalloporphyrin complex embedded therein has an SOD activity, can interact with superoxide anionic radicals (O2?.) as a target, and can reduce these radicals without fail. The niosome having a metalloporphyrin complex embedded therein can reach cells in living bodies such as cancer cells due to properties of a niosome. Therefore, the niosome having a metalloporphyrin complex embedded therein can exhibit an excellent effect of treating cancer by reducing O2?. in cancer cells. In addition, since the effect is selective, the niosome can be used as a novel anticancer agent without side effects. Moreover, the niosome having a metalloporphyrin complex embedded therein can be retained in the blood while exhibiting a superior antioxidation effect. The niosome can thus protect living bodies from hindrance brought about by active oxygen species.

  • Patent number: 8057899
    Abstract: A nano-particle composition including a poly(alkenylbenzene) core and a poly (conjugated diene) or a poly(alkylene) surface layer is provided. The nano-particles have a mean average diameter less than about 100 nm. The nano-particles can be modified via, for example, hydrogenation or functionalization. The nano-particles can advantageously be incorporated into rubbers, elastomers, and thermoplastics.

  • Patent number: 8048524
    Abstract: The present invention relates to a multilayer polymer latex comprising a seed, a rubbery core surrounding the seed, and a shell surrounding the rubbery core, in which the seed comprises a vinyl unit, a hydrophilic unit and a crosslinker unit, as well as a preparation method thereof. The present invention can provide an acrylic polymer latex and a diene polymer latex, depending on materials constituting the core and the shell. In the present invention, the seed containing a vinyl unit, a hydrophilic unit and a crosslinker unit, and the rubbery core, are used for the preparation of the polymer latex. This can increase the rubber content of the polymer latex, thus improving the impact resistance of the polymer latex, and at the same time, reduce the viscosity of the polymer latex so as to improve the long-term workability of the polymer latex upon spray drying. Thus, polymer powder prepared from the polymer latex is excellent in not only impact resistance but also flow properties.

  • Publication number: 20110260347
    Abstract: The essence of the invention is that an aqueous medium is mixed with a lipid component (lipid solution in an organic solvent) by the ejecting introduction (suction) of the lipid component (lipid solution in an organic solvent) into an ejector mixing chamber in the form of a de Laval nozzle by means of the energy from a pressurized jet of the aqueous medium flowing out of the inlet nozzle of the ejector, which jet creates a pressure drop in the convergent part (confuser) of the mixing chamber, wherein an aerosol stream of liposome is formed at the outlet of the divergent part (diffuser) of the mixing chamber.

  • Patent number: 8039015
    Abstract: Microcapsules possessing Lewis acid-Lewis base salt walls incorporate water-immiscible materials, such as N,N-diethyl-m-toluamide (DEET), as a core component. Such microcapsules, or similar microcapsules incorporating other core components, may be made by emulsifying a water-immiscible core component in an aqueous solution of one wall-forming reactant, such as the Lewis base, and then mixing that solution with the other wall-forming reactant, such as the Lewis acid. Various adjuvants may be included with the core component to contribute additional characteristics, such as enhancement of a controlled release characteristic or improved mechanical stability.

  • Patent number: 8029709
    Abstract: A process for the encapsulation of liquid particles within nanometer thick polymer shells utilizes an interfacial free radical alternating copolymerization process. Encapsulating a liquid material includes providing a mixture comprising the liquid material to be encapsulated, a hydrophobic monomer in a non-polar solution and a hydrophilic monomer in a polar solution. The liquid material is compatible in either the polar solution or the non-polar solution. The polar solution and the non-polar solution are not miscible in each other. The mixture is homogenized to form an emulsion, and then polymerized by an initiator which initiates an interfacial free radical alternating copolymerization process. The copolymerization process is optimally constrained to proceed only at the hydrophobic and hydrophilic interface thus forming a polymer around the liquid material.

  • Publication number: 20110224151
    Abstract: Disclosed are a polymer micelle composition for treatment of resistant cancer cells that contains an amphiphilic double block copolymer and taxane and a P-glycoprotein inhibitor of cyclosporin as its active ingredients, and a method of preparing the same. Said polymer micelle composition for treatment of cancer resistant cells is accumulated in cancer tissue at high concentrations, and has the advantages that it exhibits superior anti-cancer effects for the cancer cells that have exhibited resistance due to over-expression of P-glycoprotein by the taxane anticancer agent in said cancer tissue, and does not cause hypersensitive reactions due to the use of a solubilizer.
