Strategies toward development of biodegradable hydrogels for biomedical applications

Hydrogel is a macromolecular gel constructed of a network of cross-linked polymer chains. Hydrogels are class of materials that can be tuned toward the subjected stimuli and can be modified to imitate the extracellular environment of the body which makes hydrogel worthy of being used in tissue regeneration, drug delivery, and other fields of science. Hydrogels offer excellent potential as oral therapeutic systems due to inherent biocompatibility, and biodegradability. Hydrogels are having various tissue engineering and drug delivery application due to its high loading with ensured molecule efficacy, high encapsulation, variable release profile, stable, and inexpensive.
