Supercritical fluid processes for the natural products
extraction have been the focus of intensive research for more
than 30 years and commercial plants are spread worldwide. More
recently, new research interests have been growing on biomass,
materials, pharmaceuticals and so on.<span

lang="EN-US">In this talking, some applications of
supercritical fluids processing on the formation of
pharmaceutical particles are presented. Some precipitation
techniques are shown according to the role of the
supercritical fluid in the process: Rapid Expansion of
Supercritical Solutions (RESS), Gas Antisolvent (GAS),
Supercritical AntiSolvent (SAS) and Particles from
Gas-Saturated Solutions (PGSS). Three case studies are
targeted to pharmaceutical nanoparticles formation and
encapsulation in supercritical fluid medium for controlled
drug delivery systems.</span><br>
