Wound healing is a complex and dynamic process, and metabolic disturbances in the microenvironment of chronic wounds and the severe symptoms they cause remain major challenges to be addressed. The inherent properties of hydrogels make them promising wound dressings. In addition, biomembrane-based nanostructures and microstructures (such as liposomes, exosomes, membrane-coated nanostructures, bacteria and algae) have significant advantages in the promotion of wound healing, including special biological activities, flexible drug loading and targeting. Therefore, biomembrane-based nanostructure- and microstructure-loaded hydrogels can compensate for their respective disadvantages and combine the advantages of both to significantly promote chronic wound healing. In this review, we outline the loading strategies, mechanisms of action and applications of different types of biomembrane-based nanostructure- and microstructure-loaded hydrogels in chronic wound healing.
伤口愈合是一个复杂和动态的过程,慢性伤口微环境中的代谢紊乱及其引起的严重症状仍然是需要解决的主要挑战。水凝胶的固有特性使它们成为有前途的伤口敷料。此外,基于生物膜的纳米结构和微结构(如脂质体、外泌体、膜包覆的纳米结构、细菌和藻类)在促进伤口愈合方面具有显著的优势,包括特殊的生物活性、灵活的药物装载和靶向性。因此,基于生物膜的纳米结构和微结构负载的水凝胶可以弥补各自的缺点,并结合两者的优点,显著促进慢性伤口愈合。在本文中,我们概述了不同类型的基于生物膜的纳米结构和微结构负载的水凝胶在慢性伤口愈合中的加载策略、作用机制和应用。
