Abstract
The present invention is directed to a process for synthesizing nanoparticles. This process involves providing a stable emulsion containing a plurality of droplets suspended in a continuous phase. The droplets, which are encapsulated by an interfacially-active material, contain a first reactant dissolved in a dispersed phase. The process also involves contacting a gas phase containing a second reactant diluted in a carrier gas with the stable emulsion under conditions effective to permit the first reactant and second reactant to react and form nanoparticles. The present invention further relates to nanoparticle-loaded emulsions and their uses in formulations for various purposes.
