Nanocarriers for Drug Delivery by Supercritical Fluid Extraction of Emulsions

The advantage of the application of the supercritical extraction in contrast to the conventional methods to prepare micro and nanoparticles is that the product no longer is exposed to high temperatures for a long time. Furthermore, the supercritical extraction offers the possibility to reduce the content of the residual organic solvent in the final product because of the high solubility of orga...

Supercritical Drug Impregnation onto Intraocular Lenses

Supercritical impregnation is an attractive “clean” alternative to conventional soaking into liquid process, using generally organic solvents. Impregnation process can be used for the development of controlled delivery systems that can be applied in pharmaceutical and medical fields. This work focuses on the preparation of controlled drug delivery systems for ophthalmic applications through sup...

Application of Supercritical Fluid ‎Technology for Preparation of Drug Loaded ‎Solid Lipid Nanoparticles

   Small changes in pressure or temperature, close to the critical point, lead to large changes in solubility of supercritical carbon dioxide (CO2). Environmentally friendly supercritical CO2 is the most popular and inexpensive solvent which has been used for preparation of nanodrugs and nanocarriers in drug delivery system with supercritical fluid technology. Delivery...
