A process for preparing nanoparticles and microparticles is provided. The process involves forming a mixture of a polymer and a solvent, wherein the solvent is present in a continuous phase and introducing the mixture into an effective amount of a nonsolvent to cause the spontaneous formation of microparticles.
L'invention porte sur un procédé de préparation de nanoparticules et de microparticules consistant à former un mélange d'un polymère et d'un solvant où le solvant est présent en phase continue, puis à introduire le mélange dans une quantité efficace d'un non solvant ce qui provoque la formation spontanée de microparticules.
