Preparation and Characterization of Chitosan-Insulin-Tripolyphosphate Membrane for Controlled Drug Release: Effect of Cross Linking Agent

Preparation and Evaluation of Chitosan Microcapsules of Metronidazole using Tripolyphosphate Cross-linking Method

Metronidazole microcapsules with a coat consisting of alginate and the natural cationic polymer, chitosan were formulated by using tripolyphosphate cross-linking method and were investigated with a view to develop mucoadhesive microcapsules. The microcapsules were evaluated for their surface morphology, microencapsulation efficiency, in-vitro wash-off test, swelling behavior and in-vitro drug r...

Chitosan/carrageenan nanoparticles: effect of cross-linking with tripolyphosphate and charge ratios.

Chitosan/carrageenan/tripolyphosphate nanoparticles were prepared by polyelectrolyte complexation/ionic gelation, the latter compound acting as cross-linker. The incorporation of the three components in the nanoparticle matrix was assessed by analytical techniques (FTIR, XPS and TOF-SIMS). Using chitosan/carrageenan nanoparticles as control, the effect of the cross-linker in the particles prope...

Preparation and characterization of PLGA particles for subcutaneous controlled drug release by membrane emulsification.

Uniformly sized microparticles of poly(D,L-lactic-co-glycolic) (PLGA) acid, with controllable median diameters within the size range 40-140 microm, were successfully prepared by membrane emulsification of an oil phase injected into an aqueous phase, followed by solvent removal. Initially, simple particles were produced as an oil in water emulsion, where dichloromethane (DCM) and PLGA were the o...
