Recent developments in particle design using supercritical fluids

Supercritical fluid (SCF) techniques for materials precipitation have been the subject of many studies, mostly with the intention of making highly uniform particles. The SCF process is able to microencapsulate many materials that are difficult: to treat with existing techniques. It has also been able to control the morphology of materials by adjusting nucleation and growth during the production of particles. It is expected that these techniques will receive much attention in the future. This work aims to review the most recent published literature (from 2001 until the present), about particle design using gas anti-solvent and other SCF processes. (C) 2004 Elsevier Ltd.
