A new approach to treating chronic wounds: Patch brings light to wound care
Researchers at Empa in St. Gallen have developed a wound patch that releases chlorhexidine when exposed to visible LED light, allowing controlled disinfection. The system uses silica nanoparticles coated with a polymer shell containing photoswitches that swell to release the drug and contract to seal it again. The technology is still in laboratory testing and will require clinical trials before approval in Switzerland.
