Hydrogels play a crucial role due to their high-water content and 3D structure, which make them ideal for various applications in biomedicine, sensing, beyond. They can be prepared from variety of biomaterials, polymers, combinations, allowing versatility properties applications. include natural types derived collagen, gelatin, alginate, hyaluronic acid, as well synthetic based on polyethylene glycol (PEG), polyvinyl alcohol (PVA), polyacrylamide (PAAm). Each type possesses distinct properties, such mechanical strength, biodegradability, biocompatibility, tailored wound healing, contact lenses, bioprinting, tissue engineering. The hydrogels mimics environments, promoting cell growth nutrient waste exchange, supports the development functional tissues. serve scaffolds engineering applications, including cartilage bone regeneration, vascular engineering, organ-on-a-chip systems. Additionally, encapsulate deliver therapeutic agents, factors or drugs, specific target sites body. through three primary methods: physical crosslinking, relies non-covalent interactions entanglements hydrogen bonding; chemical forms covalent bonds between polymer chains create stable structure; irradiation-based where UV irradiation induces rapid hydrogel formation. choice crosslinking method depends desired hydrogel. By providing biomimetic environment, facilitate differentiation, support formation, aid regeneration damaged diseased tissues while delivering agents. This review focuses critical advancements processing routes development, summarizing characterization application hydrogels. It also details key healing challenges future perspectives field.
