Abstract
Nanoparticles are prepared by dissolving a poly(ethylene oxide) and/or poly(propylene oxide) polylactic copolymer in an organic solvent followed by formation of nanoparticles by mixing the solution containing the polymer with an aqueous solution and by precipitation, without using an additional colloidal protective agent or by microfluidization and solvent evaporation. Nanoparticles prepared by this method are disclosed.
