Abstract
Impaired angiogenesis and excessive inflammation are major factors contributing to delayed wound healing in diabetic patients. This study presents the development of a novel multifunctional hydrogel, Pltm@CNPs/Gel, which incorporates platelet membrane camouflaged cerium nanoparticles into a gelatin methacryloyl matrix. The Pltm@CNPs/Gel nanocomposite hydrogel was characterized and tested for its effects on platelet activation, coagulation, cell viability, anti-oxidation, and anti-inflammation in vitro. Moreover, we evaluated the wound healing potential of the hydrogel in a diabetic rat model. Our findings demonstrate that the Pltm@CNPs/Gel hydrogel possesses anti-oxidative and anti-inflammatory properties. Furthermore, it accelerates diabetic wound healing by promoting neovascularization, cell proliferation, and collagen fiber organization. This study highlights the potential of the Pltm@CNPs/Gel hydrogel as a therapeutic option for diabetic wound healing and its promising applications as a diabetic wound dressing candidate.
