Review reveals design strategies for polyphenol-integrated gelatin bioadhesives in wet tissue repair, indicating broad therapeutic potential for sutureless wound management.

Key Points

Summarize recent advances in polyphenol-functionalized gelatin bioadhesives and evaluate fabrication strategies, functional benefits, and obstacles to clinical translation.
Reviewed biomimetic engineering strategies incorporating phenolic moieties—such as catecholamines, phenolic amino acids, tannins, and lignins—into gelatin backbones.
Assessed processing and fabrication approaches, including chemical infusion, physical blending, and copolymerization, relative to cross-linking compatibility.
Polyphenolic compounds establish covalent and noncovalent interactions with tissue substrates like keratins and soft internal organs, while acting as cross-linkers to improve hydrogel cohesion.
Synthetic and natural polyphenolic additions introduce multifunctional attributes to gelatin networks, including photothermal responsiveness and antimicrobial activity.
Key manufacturing hurdles involve low-yield functionalization chemistry, constrained protein-binding capacity, and phenolic free-radical scavenging that disrupts free-radical polymerization.
