Probing insulin bioactivity in oral nanoparticles produced by ultrasonication-assisted emulsification/internal gelation
Alginate-dextran sulfate-based particles obtained by emulsification/internal gelation technology can be considered suitable carriers for oral insulin delivery. A rational study focused on the emulsification and particle recovery steps was developed in order to reduce particles to the nanosize range while keeping insulin bioactivity. There was a decrease in size when ultrasonication was used dur...
متن کاملCharacterization of insulin-loaded alginate nanoparticles produced by ionotropic pre-gelation through DSC and FTIR studies
Insulin-loaded nanoparticles were prepared by ionotropic pre-gelation of alginate with calcium chloride followed by complexation between alginate and chitosan. The influence of the pH and stoichiometry relationship between polyelectrolytes providing individual particles with a nano-scale size was assessed by photon correlation spectroscopy (PCS) and scanning electron microscopy (SEM). Insulin– ...
متن کاملDiffractive optical devices produced by light-assisted trapping of nanoparticles.
One- and two-dimensional diffractive optical devices have been fabricated by light-assisted trapping and patterning of nanoparticles. The method is based on the dielectrophoretic forces appearing in the vicinity of a photovoltaic crystal, such as Fe:LiNbO3, during or after illumination. By illumination with the appropriate light distribution, the nanoparticles are organized along patterns desig...
متن کاملChitosan-based nanoparticles by ionotropic gelation
Ionotropic gelation between chitosan, as the polycation of acidic pH, and TPP (penta sodium triphosphate aka tripolyphosphate) as the anionic oligomeric partner leads to the formation of colloidal systems which can range from approximately 100nm to 2000nm. Depending on the conditions, particles with different properties can be obtained including differences in size, zeta potential, stability at...
متن کاملOptimization and development of insulin nanoparticles by new thiolated chitosan derivative with ionic gelation method using a model-based methodology
Insulin therapy has been the best choice for the clinical management of diabetes mellitus. The current insulin therapy is via subcutaneous injection, which often fails to mimic the glucose homeostasis that occurs in normal individuals. Oral delivery is the most convenient administration route. However, insulin cannot be well absorbed orally because of its rapid enzymatic degradation in the gast...
