Abstract
Surface-modified nanoparticles are produced by associating ligand interactive agents with the surface of a nanoparticle. The ligand interactive agents are bound to surface modifying ligands that are tailored to impart particular solubility and/or compatibility properties. The ligand interactive agents are crosslinked via a linking/crosslinking agent, such as hexamethoxymethylmelamine or a derivative thereof. The linking/crosslinking agent may provide a binding site for binding the surface modifying ligands to the ligand interactive agents.
Claims17
A method of functionalizing an InP/ZnS nanoparticle, comprising:
- associating, in a solvent, a ligand interactive agent comprising a C8-C20 fatty acid with the nanoparticle to form a mixture comprising a ligand interactive agent-nanoparticle association complex;
- adding a linking/crosslinking agent comprising a melamine and a surface modifying ligand to the mixture;
- and
- reacting the ligand interactive agent-nanoparticle association complex, the linking/crosslinking agent and the surface modifying ligand to form a functionalized nanoparticle having an outer surface comprising the surface modifying ligand.
A composition comprising an InP/ZnS nanoparticle and a melamine compound.
