Polymer coating/encapsulation of nanoparticles using a supercritical anti-solvent process
Coating or encapsulation of nanoparticles is a major challenge due to the extremely small size, high surface energy, and high surface area of the nanoparticles. In this paper we describe a new method using supercritical CO2 as an anti-solvent (SAS) for nanoparticle coating/encapsulation. A model system, using silica nanoparticles as host particles and Eudragit polymer as the coating material, w...
متن کاملSupercritical Anti-solvent Precipitation of Sodium Ibuprofen
In recent years, significant effort has been devoted to the development of drug formulation with the purpose of targeting and controlled release. The micro/nanosizing of drugs has been identified as a potentially effective and broadly applicable approach. In the pharmaceutical industry several conventional techniques have been utilized for particle size reduction. The disadvantages of these tec...
متن کاملPreparation of Liposome Precursors by Supercritical Anti-solvent Techniques
The possibility of preparation of hydrogenated phosphatidylcholine (HPC) liposome precursors (LP) using supercritical anti-solvent technology (SAS) was evaluated. Vitamin D (VD) and coenzyme Q10 (CoQ10) were chosen as the model drugs, and HPC was used as the wall material. The influences of operation conditions (pressures, concentrations and etc.) on the HPC were studied. The structure of the L...
متن کاملMicronisation of Ethyl Cellulose by Supercritical Anti-solvent Process
Supercritical Anti-Solvent (SAS) process is considered as a clean technology suitable for particle design, micron or nanometer sized. It is generally used to micronize compounds of interest in mild operating conditions of temperature and nearly without any residual solvent traces in the end-product. By varying the process parameters, the properties of the produced powders can be adjusted with a...
متن کاملPreparation of acetazolamide composite microparticles by supercritical anti-solvent techniques.
The possibility of preparation of ophthalmic drug delivery systems using compressed anti-solvent technology was evaluated. Eudragit RS 100 and RL 100 were used as drug carriers, acetazolamide was the model drug processed. Compressed anti-solvent experiments were carried out as a semi-continuous or a batch operation from a liquid solution of polymer(s)+solute dissolved in acetone. Both technique...
