Alginate-Based Hydrogel Blends with Uncrosslinked Polymers: Multiscale Structure and Its Relationship with Viscoelastic Properties
The multiscale architecture of alginate–gelatin–hyaluronic acid (AGH) hydrogels was elucidated using a synergistic approach of swelling tests, mechanical characteristics, TEM, and SAXS; it was demonstrated that, in AGH, a crosslinked alginate network coexists with non-interconnected cavities composed of uncrosslinked...
