Abstract:
1. A method comprising: (a) providing a first solution mixture comprising at least one nanoparticle precursor and at least one first solvent for the nanoparticle precursor, wherein the nanoparticle precursor comprises a salt comprising a cation comprising a metal; (b) providing a second solution mixture comprising at least one reactive moiety reactive for the nanoparticle precursor and at least one second solvent for the reactive moiety, wherein the second solvent phase separates when it is mixed with the first solvent; and (c) combining said first and second solution mixtures in the presence of a surface stabilizing agent, wherein upon combination the first and second solution mixtures phase-separate and nanoparticles having a surface stabilizing layer disposed thereon are formed, and further comprising the step of collecting the nanoparticles, wherein the collected nanoparticles have an average particle size of about 1 nm to about 100 nm, and wherein a thickness of the surface stabilizing layer disposed on the nanoparticles is less than a diameter of the nanoparticles.
