Advancing biomedicine with gel‐based materials and composites: A comprehensive review

Abstract Polymer gels are an important class of soft materials with growing interest for biomedical applications due to their distinctive properties. These three‐dimensional polymer networks capable imbibing large amounts solvent while maintaining solid‐like behavior. can be classified into hydrogels, aerogels, and cryogels based on structural features. Their highly porous structure, swelling capacity, biocompatibility make them well‐suited diverse uses in biomedicine. Recent advances have enabled the engineering tunable architectures smart functionality responsive stimuli. developments expanded potential areas like tissue engineering, drug delivery, wound healing, biosensing. However, toxicity remains consideration use. Careful design toxicological evaluation is essential ensure safe clinical application. Overall, offer new possibilities biomedicine through continued research synthesizing biocompatible elucidating structure–function relationships. This review provides updated perspective progress promise tailoring advance biomedicine, also considering critical aspect biocompatibility.
