    摘要： A surface treated particle comprising a plurality of inorganic, metallic, semi-metallic, and/or metallic oxide particles and a star-graft copolymer with looped and/or linear polymeric structure on a star-graft copolymer, obtainable by a heterogeneous polymerization reaction in the particle surface proximity, encapsulating at least a portion of said particles and a method for making the same. The surface treatment comprises: Si (w, x, y, z), where: w, x, y, and z are mole percent tetrafunctional, trifunctional, difunctional, and monofunctional monomeric units, respectively; w, x, y, and z are about 0-50, 0-50, 5 - 99, and 0-5, respectively; w is tetraethylorthosilicate; x is selected from the group consisting of Ϝ-glycidoxypropyltrimethoxysilane, Ϝ-methacryloxypropyltrimethoxysilane, methyltrimethoxysilane, n-propyltrimethoxysilane, isobutyltrimethoxysilane, n-hexyltrimethoxysilane, n-octyltrimethoxysilane, n-octadecyltrimethoxysilane, phenyltrimethoxysilane, 3-(trimethoxysilyl)propylsuccinic anhydride, heptadecafluorotrimethoxysilane, 3-isocyanatopropyltrimethoxysilane, 2-(diphenylphosphino)ethyltrimethoxysilane, 3-aminopropyltrimethoxysilane, 3-mercaptopropyltrimethoxysilane, n-(trimethoxysilylpropyl)EDTA, pentafluorophenylpropyltrimethoxysilane, trifluoropropyltrimethoxysilane, and the triethoxy-containing counterparts of these monomers; y is selected from the group consisting of dicyclohexyldimethoxysilane, diethyldiethoxysilane, dimethyldichlorosilane, dimethyldiethoxysilane, dimethyldimethoxysilane, diphenyldiethoxysilane, diphenyldimethoxysilane, di-n-hexyldichlorosilane, n-hexylmethyldichlorosilane, methyldodecyldiethoxysilane, n-octylmethyldimethoxysilane, and the diethoxy-containing counterparts of these monomers; and z is selected form the group consisting of n-octadecyldimethylmethoxysilane, triethylsilanol, trimethylethoxysilane, trimethylmethoxysilane, and the ethoxy-containing counterparts of these monomers. Product(s) per se, defined as surface treated ZnO and/or TiO2, and the use of the product(s) per se in personal care formulations are excluded.

    摘要： Functionalized fluorescent nanocrystal compositions and methods for making and using these compositions are disclosed. The compositions are fluorescent nanocrystals coated with at least one material. The coating material has chemical compounds or ligands with functional groups or moieties with conjugated electrons and moieties for imparting solubility to coated fluorescent nanocrystals in aqueous solutions. The coating material provides for functionalized fluorescent nanocrystal compositions which are water soluble, chemically stable, and emit light with a high quantum yield and/or luminescence efficiency when excited with light. The coating material may also have chemical compounds or ligands with moieties for bonding to target molecules and cells as well as moieties for cross-linking the coating. In the presence of reagents suitable for reacting to form capping layers, the compounds in the coating may form a capping layer on the fluorescent nanocrystal with the coating compounds operably bonded to the capping layer.
