Preparation and Characterization of Quaternized Chitosan Coated Alginate Microspheres for Blue Dextran Delivery
In this study, 2-[(Acryloyloxy)ethyl]trimethylammonium chloride was graft polymerized onto chitosan (CS) to form quaternary ammonium CS (QAC) by using ammonium persulfate as a redox initiator. Alginate (ALG) microspheres loaded with a water-soluble macromolecular model drug, blue dextran (BD), were obtained by corporation of coaxial gas-flow method and ionic gelation process. CS and QAC were th...
متن کاملPreparation of alginate coated chitosan microparticles for vaccine delivery
BACKGROUND Absorption of antigens onto chitosan microparticles via electrostatic interaction is a common and relatively mild process suitable for mucosal vaccine. In order to increase the stability of antigens and prevent an immediate desorption of antigens from chitosan carriers in gastrointestinal tract, coating onto BSA loaded chitosan microparticles with sodium alginate was performed by lay...
متن کاملIsoniazid loaded chitosan microspheres for pulmonary delivery: Preparation and characterization
The objective of the present study was to entrap isoniazid, an Antitubercular drug, in cross linked chitosan matrix and study in vitro lung deposition of powdered chitosan microspheres using Andersen cascade impactor. Ionic cross linker Tripolyphospate was used to make cross linked chitosan microspheres to achieve sustained drug release. Chitosan microspheres were prepared by spray drying metho...
متن کاملPreparation and Characterization of Radiopaque Chitosan Microspheres
Polymeric beads with diameter in the micrometer range find use in vanous medical applications, such as bone cements', in local delivery of drugs' and in treatment of female stress urinary incontinence.r" Medical microspheres usually consists of poly (methyl methacrylate), poly (lactic acid-eo-glycolic acid), poly (tetra fluoroethylene) or silicone rubbers. A particularly important application o...
متن کاملPreparation and characterization of PEG/Dextran coated superparamagnetic Iron Oxide (Fe3O4) nanoparticles for biomedical applications
Recent progress in nanotechnology and electrochemical methods can be applied to fine control of the size, crystal structure, and surface properties of iron oxide nanoparticles. Here we appliedcathodic electrochemical deposition (CED) as an efficient and effective tactic for synthesisand double coating of surface of superparamagnetic iron oxide nanoparticles (SPIONs). In first step, bare Fe3O4 n...
