Coating and encapsulation of fine particles with polymer using a supercritical antisolvent (SAS) coating process was investigated in this research. Synthesized submicron silica particles were used as host particles and poly(lactide-co-glycolide) (PLGA), a biodegradable polymer used for controlled release of drugs, was chosen as the coating material. In the SAS coating process a suspension of si...

Particle size reduction is effective in increasing the dissolution rate and bioavailability of poorly water-soluble drugs. However, obtaining microparticles without a distribution or even with narrow difficult conventional methods, such as milling antisolvent precipitation. In novel method used this study, uniformly sized droplets drug solution were first prepared on polydimethylsiloxane film, ...

Plant extracts having an inhibitory effect on aging may be a good choice for cosmetic applications because of their natural origin. The extraction of bioactive compounds from plants is one of the most critical steps in the commercial development of natural products. Therefore rapid and efficient phytochemical extraction methods are essential. The present study involves the use of microwave and ...

Nanocrystalline cellulose (NCC) with small particle size and high crystallinity was prepared via the combined method of ultrasonication and acid hydrolysis from bleached softwood kraft pulp (BSKP). Scanning electron microscopy, transmission electron microscopy, X-ray diffraction (XRD), and Fourier transform infrared spectroscopy were used for determination of morphology, crystal structure, and ...
