A Review on Biocompatible Hydrogel: Formulation Aspect and Evaluation

Many predefined ways are now a day adopted to interface with biological tissues. One such significant class of biomaterials are hydrogels, which are defined as highly hydrated materials. Hydrogels are designed to absorb a large amount of water or biological fluids due to its three-dimensional, hydrophilic, polymeric network. They closely simulate natural living tissue, more so than any other class of synthetic biomaterials because of their high-water content, porosity,and soft consistency.They are chemically stable but may degrade and gradually disintegrate up to dissolve. Now a day they become more popular because of their unique property of flexibility and biocompatibility. Hydrogels can be produced by both natural and synthetic polymers. These polymers undergo physical and chemical cross-linking to produce hydrogels. Due to their resemblance to the living tissue, they have the immense possibility to use hydrogels in the biomedical field. Some of the well-known use of hydrogels include manufacturing contact lenses, hygiene products, tissue engineering scaffolds, drug delivery system and wound dressings. The current review article deals with information about the hydrogels, their various types, preparation methods along with an evaluation of the same.Also, the present study is performed for the motivation of the graduates towards publication and research. Hence, we have encouraged the graduates to prepare an informative article on the present subject.
