Shinji Takeoka tells Nanowerk. "We found that our ultra-thin PLLA nanosheet has an excellent sealing efficacy for gastric incision as a novel wound dressing that does not require adhesive agents. Furthermore, the sealing operation repaired the incision completely without scars and tissue adhesion. This approach would constitute an ideal candidate for an alternative to conventional suture/ligation procedures, from the perspective not only of a minimally invasive surgical technique but also reduction of operation times."
Takeoka and colleagues have published their findings in a recent paper in Advanced Materials ("Free-Standing Biodegradable Poly(lactic acid) Nanosheet for Sealing Operations in Surgery").
