Researchers at Harvard Medical School and Brigham and Women's Hospital are developing medical adhesives based on spider webs, a parasitic worm and porcupine quills. The spiny-headed worm inspired an adhesive that holds skin grafts in place with microneedles, and spider webs inspired a neonatal adhesive that does not damage fragile skin when it is removed, researcher Jeffrey Karp said. Porcupine quills inspired a patch that could replace sutures or staples.
