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 [OCHCH]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.

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 [&#x2014;OCHCH], 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.
