Abstract:
1. A method of forming a dispersion of nanoparticles, comprising: incorporating the nanoparticles into first coordination complexes comprising the nanoparticles coordinated to ligands with relatively low water solubility; the first coordination complexes being dispersed within a non-polar solvent; while the first coordination complexes are within the non-polar solvent, and while the ligands remain coordinated with the nanoparticles, reacting the ligands with one or more reactants to increase the water solubility of the ligands without severing coordination of the nanoparticles to the ligands and thereby to convert the first coordination complexes into second coordination complexes having relatively high water solubility and including the nanoparticles coordinated to the reacted ligands; while the second coordination complexes are within the non-polar solvent, combining the non-polar solvent with water; and extracting the second coordination complexes from the non-polar solvent into the water.
