Abstract

Hydrogels and hybrid hydrogels, methods of making the hydrogels/hybrid hydrogels, and methods of using the hydrogels/hybrid hydrogels. The hydrogels have polysaccharide moieties (e.g., chitosan or hyaluronic acid moieties). The hybrid hydrogels have polysaccharide moieties (e.g., chitosan or hyaluronic acid moieties) and poly(ester amide) moieties. The poly(ester amide) moieties can have one or more arginine moieties. The hydrogels/hybrid hydrogels can be used, for example, in consumer products and as cargo carrier materials (e.g., as therapeutic agent carriers).
