Free-standing biodegradable poly(lactic acid) nanosheet for sealing operations in surgery

Abstract

(Figure Presented) A free-standing biodegradable nanosheet composed of poly(L-lactic acid) (PLLA) was shown to have excellent sealing efficacy for a gastric incision as a novel wound dressing material that did not require adhesive agents, and the PLLA nanosheet-induced wound repair showed neither scars nor tissue adhesion. This material may, therefore, be an ideal alternative to conventional tissue repairing procedures using suture/ligation in surgery. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
