Egg albumin microspheres containing pilocarpine nitrate were prepared by heat stabilization method. Factors affecting size and encapsulation efficiency were optimized to obtain microspheres in the size range 1 to 12 μm to make them undetectable by eyes and big enough to entrap drug efficiently. Encapsulation efficiency was found to be 62.5%. In vitro release of drug from microspheres followed s...

This article describes the preparation and characterization of anticancer drug-loaded poly(lactide-coglycolide) (PLGA) microparticles. PLGA microparticles loaded with doxorubicin HCl (DOX) were prepared via o/w emulsion solvent evaporation. The release characteristics, encapsulation efficiency, size, and morphology of the PLGA microparticles were also determined. A cytotoxicity test was perform...

Preparation and in vitro characterization of floating microparticles loaded with cimetidine (FMC) for oral delivery was the objective of this study. Non-solvent addition coacervation technique using hydroxypropylmethylcellulose (HPMC) as the rate controlling polymer was employed to achieve FMC. Three formulations of FMC were prepared and optimized regarding encapsulation efficiency and dissolut...

        The purpose of this study was to prepare and characterize microspheres loaded by cyclosporine A(CyA)-cyclodextrin (CD) complex. To achieve this goal, PLGA microspheres loaded by CyA CD complex were prepared by multiple emulsificationsolvent evaporation methods.Morphology, size, encapsulation efficiency and drug release from these microspheres were evaluated. Microscopic evaluation of mi...

This study aims to investigate the capability of forming itraconazole containing niosomes with Span 60 and Brij 58 as non-ionic surfactants. Lower cost and higher stability makes niosomes a more suitable choice in comparison with liposomes.The capability to form vesicles as an itraconazole delivery system and the influence of different factors such as type of surfactant and molar ratio of chole...

Recombinant human insulin was encapsulated within alginate microspheres by the emulsification/internal gelation technique with the objective of preserving protein stability during encapsulation procedure. The influence of process and formulation parameters was evaluated on the morphology and encapsulation efficiency of insulin. The in vitro release of insulin from microspheres was studied under...

In this work, we propose and develop the inorganic salt encapsulation of semiconductor nanocrystal (NC) dispersion in a nonpolar phase to make a highly stable and highly efficient colour converting powder for colour enrichment in light-emitting diode backlighting. Here the wrapping of the as-synthesized green-emitting CdSe/CdZnSeS/ZnS nanocrystals into a salt matrix without ligand exchange is u...

In most cases, vascularization is the first requirement to achieve tissue regeneration. The delivery from implants of angiogenic factors, like VEGF, has been widely investigated for establishing a vascular network within the developing tissue. In this report, we investigated if encapsulation of VEGF in nanoparticles could enhance angiogenesis in vivo as compared to free VEGF when incorporated i...

the goal of this study was to prepare and characterize alginate microspheres as an antigen delivery system and adjuvant for immunization against leishmaniasis. microspheres encapsulated with autoclaved leishmania major (alm) and quillaja saponin (qs) were prepared by an emulsification technique and characterized for size, encapsulation efficiency and release profile of encapsulates. selection o...
