Particle Production by Supercritical Antisolvent Processing Techniques
This thesis discusses particle production by supercritical antisolvent processing (SAS) techniques by looking the fundamentals and applications of the method with some case studies. The final aim of this work is however to consider the SAS particle production process feasibility. In the process studied the solid is dissolved in a conventional solvent and the solution is sprayed continuously thr...
متن کاملApplication of supercritical antisolvent method in drug encapsulation: a review
The review focuses on the application of supercritical fluids as antisolvents in the pharmaceutical field and demonstrates the supercritical antisolvent method in the use of drug encapsulation. The main factors for choosing the solvent and biodegradable polymer to produce fine particles to ensure effective drug delivery are emphasized and the effect of polymer structure on drug encapsulation is...
متن کاملEffect of supercritical fluid density on nanoencapsulated drug particle size using the supercritical antisolvent method
The reported work demonstrates and discusses the effect of supercritical fluid density (pressure and temperature of supercritical fluid carbon dioxide) on particle size and distribution using the supercritical antisolvent (SAS) method in the purpose of drug encapsulation. In this study, paracetamol was encapsulated inside L-polylactic acid, a semicrystalline polymer, with different process para...
متن کاملSupercritical antisolvent precipitation of PHBV microparticles.
The micronization of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) from organic solutions using supercritical antisolvent (SAS) technique has been successfully achieved. SAS experiments were carried out at different operational conditions and microspheres with mean diameters ranging from 3 to 9 microm were obtained. The effect of CO(2) and liquid flow, temperature and pressure on particle...
