Hydrogel Bioadhesives
In article number 2202285, Ji Liu and co‐workers report sealing gastric perforations with a hydrogel bioadhesive, which integrates an acid‐tolerant hydrogel substrate and an adhesive polymer brush layer. The hydrogel bioadhesive enables instant, atraumatic, fluid‐tight, and sutureless sealing of gastric perforations, as well as a robust biointerface in direct contact with gastric...
Hydrogel bioadhesives have emerged as one of the most promising alternatives to sutures and staples for wound sealing and repairing, owing to their unique advantages in biocompatibility, mechanical compliance, and minimally invasive manipulation. However, only a few hydrogel bioadhesives have been successfully used for gastric perforation repair, due to their undesirable swelling when in direct contact...
