  • 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.
    Type: Grant
    Filed: June 4, 2010
    Date of Patent: October 27, 2015
    Assignee: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (C.N.R.S.)

  • Method for preparing a water-compatible composition of metal oxide nanocrystals and the water-compatible composition obtained
    Patent number: 9162900
    Abstract: A method for preparing a composition of metal oxide nanocrystals from at least one organometallic precursor in an aprotic solvent in the presence of at least one PEG ligand including a carbon chain having at least one end functionalized by a coordinating group containing at least one heteroatom, and at least one [—OCH2CH2]n, group, such that it is soluble in both the aprotic solvent medium and in water. The resulting water-compatible and organocompatible composition of metal oxide nanocrystals is also described.
