Abstract: Microneedles are demonstrated as an effective strategy for chronic wound treatment. Great endeavors are devoted to developing microneedles with natural compositions and potent functions to promote therapeutic effects for wound healing. Herein, a novel graphene oxide-integrated methacrylated fish gelatin (GO-FGelMA) microneedle patch encapsulated with bacitracin and vascular endothelial growth factor (VEGF) is developed for chronic wound management. As the natural components and porous structures of FGelMA, the fabricated microneedle patches display satisfactory biocompatibility and drug-loading ability. Owing to the integration of graphene oxide, the microneedle patches can realize promoted drug release via near-infrared (NIR) irradiation. Besides, the encapsulated bacitracin and VEGF endow the microneedle patches with the ability to inhibit bacterial growth and promote angiogenesis. It is demonstrated that the GO-FGelMA microneedle patches with efficient drug release exert a positive influence on the wound healing process through reduced inflammation, enhanced wound closure, and improved tissue regeneration. Thus, it is believed that the proposed drugs-loaded GO-FGelMA microneedle patches will hold great potential in future chronic wound treatment.
