An interdisciplinary team of Cornell researchers developed a nanofiber-coated cotton bandage that utilizes the antibiotic and environmentally sustainable properties of Lawsone, a ring-shaped compound found in henna leaves. A bandage that can both fight infection and enhance healing must have bioactive agents — compounds that directly influence the biological function of cells and can therefore be used in biomedical applications. Many cotton-based bandages on the market add cost-efficient synthetic materials such as polyester to enhance wound healing. To combat this low solubility while still using sustainable materials, the team used cyclodextrin, a large molecule that binds Lawsone. As for future developments, the team seeks to expand upon their research by using alternative materials like Curcumin and Quercetin.
