Natural polymer‐based adhesive hydrogel for biomedical applications

Hydrogel is a polymer network system that can form hydrophilic three-dimensional structure through different cross-linking methods. In recent years, hydrogels have received considerable attention due to their good biocompatibility and biodegradability by introducing mechanisms functional components. Compared with synthetic hydrogels, natural polymer-based low biotoxicity, high cell affinity, great potential for biomedical fields; however, mechanical properties tissue adhesion capabilities been unable meet clinical requirements. many efforts made solve these issues. this review, the progress in field of adhesive highlighted. The authors first introduce general design principles being used as excellent adhesives challenges associated design. Next, usages applications are summarised, such wound healing, haemostasis, nerve repair, bone cartilage electronic devices, other repairs. Finally, presented.
