A process for the production of surface functionalised nanoparticles, such as the production of semiconductor quantum dot nanoparticles incorporating surface-bound functional groups that increase the ease with which the dots can be employed in applications, such as incorporation into solvents, inks, polymers, glasses, metals, electronic materials and devices, bio-molecules and cells. Embodiments of the method include reacting first and second nanoparticle precursor species in the presence of a nanoparticle surface binding ligand X&#x2014;Y&#x2014;Z where X is a nanoparticle surface binding group, Y is a linker group, and Z is a functional group, in which Y comprises a polyethyleneglycol group and/or Z comprises an aliphatic group incorporating a terminal unsaturated group, the reaction being effected under conditions permitting binding of said surface binding ligand to the growing nanoparticles to produce said surface functionalised nanoparticles.

Surface functionalised nanoparticles

Embodiments of the invention relate to a process for the production of surface functionalised nanoparticles, such as semiconductor quantum dot nanoparticles incorporating surface-bound functional groups suitable for enabling the dots to be incorporated into silicone polymers.

Nanoparticles including a molecular cluster compound incorporating ions from groups 12 and 16 of the periodic table, as well as a core semiconductor material incorporating ions from groups 13 and 15 of the periodic table, are fabricated. The core semiconductor material is provided on the molecular cluster compound.
