TLDR The smart bandage improved healing in diabetic mice by delivering drugs directly into wounds.
The study developed a wirelessly controlled smart bandage with 3D-printed miniaturized needle arrays designed to deliver drugs directly into deeper layers of chronic wound beds. This programmable platform allowed for the active delivery of various drugs with independent temporal profiles, which was crucial for effective wound healing. The research demonstrated that delivering vascular endothelial growth factor (VEGF) using this method significantly improved wound closure, re-epithelialization, angiogenesis, and hair growth in chronic dermal wounds of diabetic mice compared to standard topical delivery methods. This highlighted the importance of both the choice of therapeutics and the delivery method in treating chronic wounds.
