 Nature: Smart Way to Seal Cuts

 

As “Research Highlights This Week”,gave a report entitled “Smart Way to Seal Cuts” on 30 Aug 2012. A ‘smart’ suture that doublesas a heater and a thermometercould promote wound healing.John Rogers of theUniversity of Illinois atUrbana-Champaign and hiscolleagues have developed aprototype silicon-based suture(pictured) that is long, thinand flexible enough to besewn into a wound. The suturecontains circuit elementsthat can both heat tissueand sense its temperature.This enables the device tokeep the wound at an idealtemperature for healing and todetect temperature increasesassociated with infection.The researchers hopeto develop sutures withother functions, such asprogrammable drug release.Small http://dx.doi.org/10.1002/smll.201200933 (2012)
