摘要
Wound delayed healing or non-healing has seriously affected patients’quality of life and has been a significant economic burden for public health systems worldwide.Excess reactive oxygen species(ROS)play important roles for impeding the process of wound healing.Herein,we report a hydrogel system containing low-valence-state molybdenum nanomaterials(Mo hydrogel)for wound healing by scavenging the detrimental ROS.Both in vitro and in vivo results demonstrate that the synthesized Mo hydrogel can accelerate wound healing,promote angiogenesis,and stimulate the expression of growth factors.Since the molybdenum is an essential element for the survival of all organisms,such novel Mo-hydrogel has the great potential to be clinically translated for wound healing.
