An adhesive dressing populated with hydrogel-anchored microneedles promises to revolutionize the on-site treatment of hemorrhaging wounds. UCLA bioengineers will be publishing this remarkable discovery in the May, 2023 edition of the Bioactive Materials journal. The tiny prongs jump-start blood clotting and quickly squelch the flow of blood. Testing the microneedle bandage in the bleeding rat liver model in comparison to a hydrogel-only dressing showed that the microneedles reduced the time till clot formation from 11.5 to 1.3 minutes and the loss of blood by more than 90%.
