标题:Liposome-assisted synthesis of polymeric nanoparticles
发明人：PERROTT MICHAEL G; BARRY STEPHEN E
权利人:ALNIS LLC
摘要:Synthetic polymer complements (SPCs) are provided, as well as methods for their synthesis and use. The SPCs range in size from about 20 to about 1000 nm. The SPCs have surfaces that are complementary to surface sites of target molecules, resulting in the ability of the SPCs to selectively bind to molecular targets. The molecular recognition capability of these particles enables their use in diagnostic, therapeutic, and separation applications. The SPC is formed by contacting a target template molecule with a set of building blocks solubilized in the interior of a liposome, which building blocks are then polymerized into a network to form the synthetic polymer complement in the interior of the liposome. The target templates are removed to produce complementary sites in a SPC that map the surface of the target, resulting in a water-soluble SPC nanoparticle of similar dimensions as the interior of the liposome that originally supported it and capable of molecular recognition.

权利人:ISP INVESTMENTS INC; ISP INVESTMENTS LLC
摘要:Methods for the treatment of irritations of the skin and skin appendages caused by microbial stresses are disclosed. The methods include providing a composition comprising a linseed extract, obtained from hydrolysis of linseed proteins, as an active antimicrobial agent in a physiologically acceptable medium, and topically applying the linseed extract onto the skin in need thereof. The methods may be useful in the cosmetic and pharmaceutical field and, more particularly, in the field of dermatology. Cosmetic methods for reinforcing the chemical barrier function of healthy and/or sensitive skin and skin appendages are also disclosed that include the same or similar composition and steps.

标题:Biocatalytic manufacturing of (meth) acrylylcholine or 2-(N, N-dimethylamino) ethyl (meth) acrylate
发明人：HUGHES JONATHAN; SYMES KENNETH CHARLES
权利人:CIBA SPEC CHEM WATER TREAT LTD
摘要:A biocatalytic method for the synthesis of 2-(N,N-dimethyl amino)ethanol and/or choline esters of acrylic acid and/or methacrylic acid comprising reacting 2-(N,N-dimethylamino)ethanol and/or choline with acrylyl-CoA and/or methacrylyl-coA in the presence of a biocatalyst with choline acetyltransferase activity. The acrylyl-CoA and/or the methacrylyl CoA is formed by the reaction of acrylate and/or methacrylate with coenzyme A in the presence of ATP and a biocatalyst with S-acetyl coenzyme A synthetase activity.

标 题:Controlled synthesis of highly monodispersed gold nanoparticles
发明人：ZHONG CHUAN-JIAN; NJOKI PETER N; LUO JIN
权利人:UNIV NEW YORK STATE RES FOUND
摘要:A method of synthesizing highly monodispersed Au nanoparticles having diameters in the range of 30-90 nm. Seed nanoparticles in a controlled concentration are combined with a precursor, also in a controlled concentration, a reducing and capping agent (e.g., sodium acrylate) in aqueous solution. Under controlled conditions of pH, temperature, and time, highly monodispersed nanoparticles having diameters in the range of 30-100 nm are produced. A relative size standard deviation of the size distribution of the resulting nanoparticles is as low as 2%.
