No scars with healing nanosheet

Biodegradable nanomaterials could prevent scarring after surgery according to Japanese researchers. They say their polyester-based nanosheets seamlessly seal up surgical incisions in mice and could make having stitches a thing of the past. 

'I think maybe, in the future, there will be no suturing - only this taping of the nanosheets to seal the incision site. Operation time will be very short and very easy and there will be no scar after the operation,' says lead researcher, Shinji Takeoka of Waseda University in Tokyo. 'This [lack of] scarring is a very good advantage for plastic surgery, for example, and for many other operations where people are anxious about scars.'  More...
