Chronic wounds are a major challenge to public health around the world and place an enormous financial burden on the government of every nation. Wound dressings that can facilitate wound healing have long been investigated. Based on the pathological characteristics of chronic wounds, in a recent issue of Matter, Zhao and colleagues reported a novel hydrogel scaffold using 3D bioprinting technology. The integration of multiple functions is well adapted to the care needs of chronic wounds and has been verified in animals with infected chronic wounds. The application of these new technologies is an important contribution to the development of new clinical dressings.

慢性伤口是全球公共卫生面临的重大挑战，给各国政府带来了巨大的财政负担。长期以来，人们一直在研究可以促进伤口愈合的伤口敷料。基于慢性伤口的病理特征，在最近一期的Matter上，Zhao 及其同事报道了一种使用 3D 生物打印技术的新型水凝胶支架。多种功能的整合很好地适应了慢性伤口的护理需求，并已在感染慢性伤口的动物身上得到验证。这些新技术的应用对新型临床敷料的开发具有重要贡献。
