Abstract:

Biodegradable polymers/drug nanoparticles have outstanding advantages in the fields of the drug targeted delivery, effective component encapsulation and medical diagnosis and so on. The nanoparticles preparation technologies from supercritical fluid have been widely studied because of its green environmental protection, many kinds of preparation methods, easy to adjust product quality according to the requirements of use, easy subsequent separation and purification, and so on. In order to obtain polymer/drug nanoparticles to meet the requirements, supercritical fluid granulation technology is one of the effective methods. The characteristics and applications of biodegradable polymer materials were discussed. Supercritical fluid and its characteristics were briefly introduced. The technological characteristics, preparing methods, basic principle and research progress on the rapid expansion of supercritical solution (RESS), supercritical anti-solvent precipitation (SAS), supercritical CO2 assisted atomization (SAA) and supercritical fluid emulsion extraction (SFEE) were mainly introduced. The development directions of polymer/drug nanoparticles prepared by supercritical fluid technology were prospected.

Key words: supercritical fluid, nanoparticles, polymers, drug
