Thus, developing a functional wound dressing has been an imperative issue.

In vitro 2,2\u2010diphenyl\u20101\u2010picrylhydrazyl (DPPH) antioxidant tests display good antioxidant ability by scavenging more than 75% ROS, and significantly increasing the antioxidant enzyme levels in vivo.

Meanwhile, real\u2010time quantitative polymerase chain reaction (PCR) (RT\u2010qPCR) and western blot assays illustrate that it can stimulate proangiogenesis by elevating the expression of angiogenesis\u2010related genes and proteins.
