A61K 49/06, A61K 9/28
US Classification:
424009320, 427002140, 977930000
Abstract:
A method for the preparation of magnetic nanoparticles coated with a noble metal is described. The method includes providing a first mixture containing a first non-polar organic solvent and uncoated magnetic nanoparticles. The first mixture is mixed with a second mixture containing a second non-polar organic solvent and ions comprising the noble metal to form a third mixture. The third mixture is mixed with an organic ligand or a fourth mixture containing an organic ligand to form a fifth mixture. The fifth mixture is reacted with a sixth mixture containing a reducing agent to form a seventh mixture containing the monodispersed magnetic nanoparticles coated with the noble metal. The monodispersed magnetic coated nanoparticles may be separated from the seventh mixture by adding a polar organic solvent or a mixture of polar organic solvents in which the nanoparticles are insoluble.

Abstract:
Nanocrystalline forms of metal oxides, including binary metal oxide, perovskite type metal oxides, and complex metal oxides, including doped metal oxides, are provided. Methods of preparation of the nanocrystals are also provided. The nanocrystals, including uncapped and uncoated metal oxide nanocrystals, can be dispersed in a liquid to provide dispersions that are stable and do not precipitate over a period of time ranging from hours to months. Methods of preparation of the dispersions, and methods of use of the dispersions in forming films, are likewise provided. The films can include an organic, inorganic, or mixed organic/inorganic matrix. The films can be substantially free of all organic materials. The films can be used as coatings, or can be used as dielectric layers in a variety of electronics applications, for example as a dielectric material for an ultracapacitor, which can include a mesoporous material. Or the films can be used as a high-K dielectric in organic field-effect transistors. In various embodiments, a layered gate dielectric can include spin-cast (e.g., 8 nm-diameter) high-K BaTiOnanocrystals and parylene-C for pentacene OFETs.

International Classification:
C01G 49/02
US Classification:
423632, 423633
Abstract:
The present invention describes methods for preparing high quality nanoparticles, i. e. , metal oxide based nanoparticles of uniform size and monodispersity. The nanoparticles advantageously comprise organic alkyl chain capping groups and are stable in air and in nonpolar solvents. The methods of the invention provide a simple and reproducible procedure for forming transition metal oxide nanocrystals, with yields over 80%. The highly crystalline and monodisperse nanocrystals are obtained directly without further size selection; particle size can be easily and fractionally increased by the methods. The resulting nanoparticles can exhibit magnetic and/or optical properties. These properties result from the methods used to prepare them. Also advantageously, the nanoparticles of this invention are well suited for use in a variety of industrial applications, including cosmetic and pharmaceutical formulations and compositions.
