The change in rheological and mechanical properties for some ionotropic cross-linked metal-alginate hydrogel complexes in particularly copper-alginate membranes in the presence of some organic solvents (benzene, toluene, xylene, carbon tetrachloride, acetone, chloroform, dichloroethane, isobutyl alcohol and ethyl alcohol) or buffer solutions (acetates, borates and universal buffers) have been i...

Alginate, a non-toxic polysaccharide isolated from brown algae, is a widely used 3-dimensional (3D) porous scaffold for the granulosa cell and follicle encapsulation. However, impurities in commercial alginate can lead to alginate biocompatibility reduction. The aim of this study was to evaluate in vitro behavior of the granulosa cells seeded on the purified alginate in varying concent...

A technique for synthesizing biocompatible hydrogels by cross-linking calcium-form poly(γ-glutamic acid), alginate sodium, and Pluronic F-127 was created, in which alginate can be cross-linked by Ca(2+) from Ca-γ-PGA directly and γ-PGA molecules introduced into the alginate matrix to provide pH sensitivity and hemostasis. Mechanical properties, swelling behavior, and blood compatibility were in...

Supercritically dried aerogels of several polysaccharides (chitin, chitosan, alginate, alginic acid, kcarrageenan, andagar) havebeencharacterisedbyphysisorptionofN2. Surface areas ashighas570m g have been measured. The nature of the functional groups of the polysaccharide significantly influences the adsorption of N2 on the surface of the aerogel. The net enthalpy of adsorption increases with t...

Wet spinning was used to manufacture fibrous alginate hydrogel wound dressings. Samples manufactured using varied operating parameters (decreased air pressure and calcium concentration or increased nozzle diameter and alginate concentration) were compared with the control samples. The changes in the fiber size, Young's modulus, swelling ratio, fetal bovine serum (BSA) release efficacy, water va...
