Nanosheets for scar free surgical stitches
Researchers at Tokyo’s Waseda University have used the biodegradable material to develop nanosheets for suture treatment which can replace Poly-L-lactide has been used previously as degradable stitches and in
drug delivery
Wounds made in mice stomatches healed without scarring the tissue when the researchteam applied sheets to incisions. Findings were published in the journal Advanced Materials. Shinji Takeoka, professor in the Department of Life Science and Medical Bioscience at Waseda University said, “This new approach would constitute a perfect candidate for an alternative to conventional suture/ligation procedures, from the perspective not only of a minimally invasivesurgical technique but it can also reduce the operation times,” The nanosheets which is only about 20 nanometers in thickness could be used for general wound dressing, but will also be very useful in endoscopic surgery, plasticsurgery and regenerative medicine. Clinical trials could still be several years away.
