Process for preparing nanoparticles.

摘要

Process for the preparation of nanoparticles by solubilising a polylactic polyethylene oxide and/or polypropylene oxide copolymer in an organic solvent and then forming nanoparticles by mixing the solution containing the polymer with an aqueous solution by precipitation without employing any additional colloidal protective agent or by microfluidisation and solvent evaporation.
