A novel pH-responsive hydrogel-based on calcium alginate engineered by the previous formation of polyelectrolyte complexes (PECs) intended to vaginal administration
(2017-10-03)
This work aimed to develop a calcium alginate hydrogel as a pH responsive delivery system for polymyxin B (PMX) sustained-release through the vaginal route. Two samples of sodium alginate from different suppliers were ...
Effect of starch filler on calcium-alginate hydrogels loaded with yerba mate antioxidants
(Elsevier, 2013-03)
A liquid extract of yerba mate (Ilex paraguariensis), with antioxidant properties was encapsulated in calcium-alginate hydrogels containing corn starch as filler at different concentrations. Hydrogel beads were characterized ...
Release of yerba mate antioxidants from corn starch–alginate capsules as affected by structure
(Elsevier, 2014-01)
Encapsulation of yerba mate (Ilex paraguariensis) extract in a proper matrix enhances the possible applications of this natural antioxidant in food systems. To start, calcium alginate capsules were used as carriers of yerba ...
Heat treatment of calcium alginate films obtained by ultrasonic atomizing: Physicochemical characterization
(Elsevier, 2015-10)
Planar films of calcium alginate were obtained using an ultrasonic atomizing device. Sodium alginate solutions of 0.6% and 0.9% (w/v) were nebulized with calcium gluconolactate solutions (gelling agent) of 0, 1, 2 and 3% ...
Microencapsulation by spray coagulation of diltiazem HCL in calcium alginate-coated chitosan
(2008)
The aim of this work was to develop a procedure for encapsulation of diltiazem HCl by spray coagulation. Factors affecting the formulations such as the effect of NaCl on the solubility of diltiazem in alginate solution, ...
