摘要
Abstract Sutures and staplers, as gold standards for clinical wound closure, usually cause secondary tissue injury and require professional technicians and equipment. The noninvasive hydrogel adhesives are used in various biomedical applications, such as wound closure, tissue sealing, and tissue regeneration, due to their remarkable properties. Recently‐developed hydrogel adhesives, especially stimuli‐responsive hydrogels, have shown great potential owing to their advantages in regulating their performance and functions according to the wound situations or external conditions, thus allowing the wounds to heal gradually. However, comprehensive summary on stimuli‐responsive hydrogels as tissue adhesives is rarely reported to date. This review focuses on the advances in the design of various stimuli‐responsive hydrogel adhesives over the past decade, including the systems responsive to pH, temperature, photo, and enzymes. Their potential biomedical applications, such as skin closure, cardiovascular and liver hemostasis, and gastrointestinal sealing, are emphasized. Meanwhile, the challenges and future development of stimuli‐responsive hydrogel adhesives are discussed. This review aims to provide meaningful insights for the further design of next‐generation of hydrogel adhesives for wound closure and tissue regeneration.
