Smart plaster could accelerate the healing of chronic wounds

Circulatory disorders, diabetes or lying in the same position for extended periods can all lead to chronic wounds that do not heal. There are hardly any effective treatment options. A materials science research team from Kiel University (CAU), together with colleagues from the University Medical Center Schleswig-Holstein (UKSH), Harvard Medical School, U.S., and Dankook University in South Korea, has developed a wound patch with enhanced healing functions which can be individually adapted for each patient. The 3D-printed patch has antibacterial properties, supplies the wound with oxygen and moisture, and supports the formation of new tissue. The properties are activated and controlled by irradiation. The scientists from materials science and medicine recently presented their concept in the scientific journal Advanced Functional Materials, where it featured as the cover story.
