The patch instead of the doctor?

Scientists have developed a miracle patch, which itself is able to determine the extent caused by skin damage". The patch is the indicator changes color during the development of wound infection.


The effect of the patch is based on the fact that infection alters the acid-base balance of the tissues. Healthy skin and uninfected wound have pH below five, and the development of infections, this figure increases to 6, 5-8, 5.




The fact that the processing and closing the wound with a bandage or plaster is not always fully protects from infection and further education suppuration. Often the infection can develop much faster than you will have time to notice and replace the bandage covering the wound. Therefore, researchers from the Fraunhofer research institution for modular solid state technologies has developed a patch-indicator, reports the Daily Mail.




An indicator, responsive to the occurrence of infection, inherent in the material of the patch. He responds by changing the pH, changing the color from yellow to purple. The developers said that they had to overcome a number of difficulties to associate the indicator with the fibers of the material, retaining its chemical stability.




The patch has already been successfully tested in the laboratory. It is planned to conduct clinical trials at the dermatological clinic of the University of Regensburg.
