Paired with a highly adhesive layer that uses chitosan, a fibrous, sugar-based substance derived from the outer skeletons of shellfish, the composite Tough Adhesive (TA) hydrogel can bond to a ...

A research team has developed an innovative injectable adhesive hydrogel for bone regeneration. This hydrogel utilizes harmless visible light to simultaneously achieve cross-linking and ...

Unfortunately, such adhesives sometimes fail. Another approach involves injecting the material directly into the deficit, in the form of a gel that subsequently hardens into a solid. While this ...

However, existing injectable hydrogels face challenges such as difficulty in maintaining their shape within the body and limited adhesive strength. Moreover, traditional methods using bone grafts ...
