Gene delivery nanoparticles fabricated by supercritical fluid extraction of emulsions

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 Fluid Extraction+supercritical Fluid Chromatography

high pressures also requires special equipment. In summary, both RESS crystallization and SAS crystallization appear to be promising methods for generating supersaturation and therefore represent alternatives to conventional crystallization. Such alternatives may prove attractive in applications such as polymer and pharmaceutical processing, or in particle design for drug delivery. It is possib...

Supercritical fluid extraction of emulsions to produce biopolymers microparticle and nanoparticle

Supercritical fluids extraction of emulsions (SEE) is an innovative technique used for the production of micro, nano-particles with controlled size and distribution. Supercritical carbon dioxide (SC-CO2) is used to extract selectively the organic solvents from the droplets of the emulsion, in which the biopolymer is dissolved, producing the precipitation of the polymer and the subsequent format...
