Abstract:
1. A method of making coated nanoparticles comprising the steps of: providing a microemulsion; providing a first aqueous solution of a first reactant and a second aqueous solution of a second reactant, the first reactant and second reactant being selected such that a solid precipitate forms upon mixing the first and second reactants together in an aqueous environment; adding the first aqueous solution to a first aliquot of the microemulsion and the second aqueous solution to a second aliquot of the microemulsion; mixing together the first and second aliquots to form a reaction mixture that reacts to form nanoparticle cores; and adding a coating agent to the cores to form coated nanoparticles.
