  • Method for preparing an organic-compatible and water-compatible composition of metal nanocrystals, and resulting composition
    Patent number: 9169127
    Abstract: A method for preparing a composition of metal nanocrystals from at least one organometallic precursor in a solvent medium in the presence of a PEG ligand, including a carbon chain, at least one end of which is functionalized by a coordination grouping including at least one hetero atom, and having at least one [OCH2CH2]n grouping, n being an integer higher than 1, so as to be soluble both in the solvent medium and in water. The water-compatible and organic-compatible composition of metal nanocrystals thus obtained is also described.

  • Method for the preparation of a composition of nanoparticles of at least one crystalline metal oxide
    Patent number: 7704413
    Abstract: The invention relates to a method for the preparation of a composition of nanoparticles of at least one crystalline metal oxide from at least one organometallic precursor. One precursor(s) which can react spontaneously to oxidation is selected; a liquid solution of the precursor(s) is produced in a solvent non-aqueous medium, and the liquid solution is placed in contact with at least one oxidant in adapted reactional conditions in order to directly result in the production of nanoparticles of crystalline metal oxide(s). The invention also relates to a composition of nanoparticles obtained in the form of a colloidal liquid solution.
