Hydrogel (also called Aquagel) is a network of polymer chains that are water-insoluble, sometimes found as a colloidal gel. in which water is the dispersion medium. Hydrogels are superabsorbent (they can contain over 99% water) natural or. synthetic polymers. Hydrogels also possess a degree of flexibility very similar to natural tissue, due to their significant water. content. Common uses for hydrogels include. currently used as scaffolds in tissue engineering.
