Recently there has been much interest in creating increadibly thin nano films that could be used instead of stitches during surgery. The hope would be to reduce the invasive nature of operations and overall operation times by negating the need for stitches.
Researchers at the University of Waseda in Tokyo have developed such a nano-sealant film from PLLA (Polylactic acid). It has had proved efficacy in gastric surgery as a replacement for stitching. What is great news is that the tissue beneath the nano-sealant film does not scar.
The nanosheet developed has many interesting attributes. It was made with high adhesivness, transparency and high flexibility all at the same time. This makes them ideal for surgical procedures.
The nanosheet is still many years away from clinical trials but it is expected that the nanosheets could be used in many types of surgey including plastic and endoscopic surgery.
