Multifunctional Sutures with Temperature Sensing and Infection Control

The next-generation sutures should provide in situ monitoring of wound condition such as temperature while reducing surgical site infection during closure. In this study, functionalized nanodiamond (FND) and reduced graphene oxide (rGO) into biodegradable polycaprolactone (PCL) are incorporated to develop a new multifunctional suture with capabilities. Incorporation FND rGO PCL enhances its tensile strength by about 43% toughness 35%. show sensing capability the range 25–40 °C based on shift zero-splitting frequency nitrogen-vacancy (NV–) centers via optically detected magnetic resonance, paving way for potential detection or excessive inflammation healing wounds. surface readily coats antibiotics reduce bacterial risk thus is promising supporting
