The bandage was physically no different from ordinary bandages, only containing a special fluid that reacts to the level of acidity. Healthy skin or skin that is formed after injury has healed acidity (pH) 5 to 6. According to Gizmag web site, the level of acidity is more than that indicates an infection. "When the pH level of 6.5 to 8.5, dressings changed color was purple," said Dr. Sabine Trupp, who led the study.

This bandage will be tested in a dermatology clinic in Germany.
