Patent ID: 8734762

Claim:
A method for preparing a perfluorocarbon nanoemulsion containing quantum dot nanoparticles, the method comprising the steps of: (a) modifying the surface of quantum dot nanoparticles with a first perfluorocarbon to form a modified quantum dot nanoparticle, wherein the quantum dot nanoparticles are coated with hydrocarbons, wherein the first perfluorocarbon is selected from perfluorohydrocarbons or amphiphilic fluorinated hydrocarbons, which have thiol, phosphine or phosphine oxide end groups, and wherein the modified quantum dot nanoparticles have a fluorine end group; (b) preparing a dispersion by dispersing the modified quantum dot nanoparticles having a fluorine end group in a second perfluorocarbon; and (c) preparing an nanoemulsion containing quantum dot nanoparticles by adding an aqueous emulsifier solution containing lipid to the dispersion, and then mixing it.
