This paper presents the fabrication of controlled release devices for anticancer drug paclitaxel using supercritical antisolvent method. The thermodynamic and hydrodynamic effects during supercritical antisolvent process on the particle properties obtained were investigated. Scanning electron microscopy was employed to study particle sizes and morphologies achieved. It was observed that increasing supercritical pressure improves the surface morphology of particles obtained, and increasing the flow rate of the organic solution jet reduces the particle sizes obtained. A modified Supercritical Antisolvent with Enhanced Mass transfer setup was developed to produce monodispersed nanoparticles with high recovery yield. High performance liquid chromatography was used to determine the encapsulation efficiency and in vitro release profiles of paclitaxel loaded particles obtained. The encapsulation efficiencies of particles obtained using the modified SASEM process were high and up to 83.5%, and sustained release of paclitaxel from the polymer matrix was observed over 36 days release. The thermogram properties of the particles were also analyzed using differential scanning calorimetry to determine the crystalline state of polymer and drug.Singapore-MIT Alliance (SMA
