Abstract

See full text

A process can be used for preparing nanoparticles containing at least one bio-resorbable polyester. The nanoparticles are in the form of a powder with a Z-Average particle size Dz in the range of 1 to 450 nm, and with a polydispersity index PDI in the range of 0.01 to 0.5. The process involves emulsion-solvent extraction or emulsion-solvent evaporation, and application of ultrasonic sound.
