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 ...

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 ...

Anti-vascular endothelial growth factor (anti-VEGF) therapy applied to solid tumors is a promising strategy, yet, the challenge to deliver these agents at high drug concentrations together with the maintenance of therapeutic ...

Alginate hydrogels are suitable for the encapsulation of biomolecules and microorganisms for the building of bioactive materials. Several alternatives to the conventional alginate formulation are being studied for a broad ...

A biocatalyst was obtained by immobilizing an enological commercial pectinase within calcium alginate hydrogels using an entrapment technique, and its catalytic activity was evaluated during different storage conditions. ...

Oxidation reactions on -OH groups at C-2 and C-3 positions of the uronic units of sodium alginate were performed with sodium periodate, and the influence of degree of oxidation on physical properties of the oxidized ...

Selective chemical modification of both β-cyclodextrin (β-CD) and sodium alginate (alg) was performed in order to produce an alginate derivative possessing pendant β-CD cavities along the chain. The latter was then fully ...

The aim of the present work is the characterization of smart auto-degradable microspheres composed of calcium alginate/high methoxylated pectin containing an alginate lyase (AL) from Sphingobacterium multivorum and ...

In this work, three methods (ethanol, HCl, and CaCl2 routes) of sodium alginate extraction–purification from brown seaweeds (Macrocystis pyrifera) were used in order to study the influence of process conditions on final ...
