Objective: In this study, it was aimed to prepare Vancomycin loaded poly(lactic acid-co-glycolic acid) (PLGA) nanoparticles that can be used parenterally in enterococcal infections. Material and Method: the different concentrations of PLGA were nanoparticles. Emulsification-solvent evaporation method preparation particles. Particle size distribution, zeta potential, encapsulation efficiency yie...

The objective of this study was to investigate and characterize incorporated propranolol HCl (Pro) within ethyl cellulose microparticle blends using the solvent evaporation method. were prepared with a water-in-oil-in-water (W/O/W) method contained same drug Propranolol (Pro). first Pro emulsion (W/O) second dispersed in an external aqueous phase, dispersion time interval (DTI) 0 60 min. morpho...

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...

• Propolis (PROP) presents valuable health properties (e.g. antioxidant). PROP inclusion in foods is limited to its hydrophilicity, strong taste and aroma. Encapsulation may protect compounds mask unpleasant flavor extracts were encapsulated using alternative polymer-carriers loadings. efficiencies yields improved compared previous studies. Propolis, a heterogeneous matrix produced by honeybees...

Although classical split and splitless injection is more than 30 years old, we only start to understand the vaporization process in the injector. Solvent evaporation determines much of the process and is the first obstacle to overcome. Videos recorded on devices imitating injectors showed that sample (solvent) evaporation is often a violent process which is poorly controlled and might well expl...
