Poor wound healing affects millions of people globally, resulting in increased mortality rates and associated expenses. The three major complications associated with wounds are: (i) the lack of an appropriate environment to enable the cell migration, proliferation, and angiogenesis; (ii) the microbial infection; (iii) unstable and protracted inflammation. Unfortunately, existing therapeutic methods have not solved these primary problems completely, and, thus, they have an inadequate medical accomplishment. Over the years, the integration of the remarkable properties of nanomaterials into wound healing has produced significant results. Nanomaterials can stimulate numerous cellular and molecular processes that aid in the wound microenvironment via antimicrobial, anti-inflammatory, and angiogenic effects, possibly changing the milieu from nonhealing to healing. The present article highlights the mechanism and pathophysiology of wound healing. Further, it discusses the current findings concerning the prospects and challenges of nanomaterial usage in the management of chronic wounds.
全球数以百万计的人受伤口愈合不良影响,导致死亡率上升及相关费用增加。与伤口相关的三大主要并发症为:(i)缺乏适宜细胞迁移、增殖和血管生成的环境;(ii)微生物感染;(iii)不稳定且迁延的炎症。遗憾的是,现有的治疗方法尚未完全解决这些主要问题,因此其医学成效不足。多年来,将纳米材料的卓越特性整合到伤口愈合领域已产生显著成果。纳米材料可通过抗菌、抗炎和促血管生成作用刺激众多有助于伤口微环境的细胞和分子过程,可能将微环境从不愈合转变为愈合。本文着重介绍伤口愈合的机制和病理生理学。此外,还讨论了目前关于纳米材料用于慢性伤口管理的前景和挑战的研究结果。
