Researchers at the University of Bath have created a color-changing bandage that alerts wearers when they are about to get an infection. A mere prototype, this smart bandage glows fluorescent green when the wound has gotten more serious.
Created by biophysical chemistry professor Toby Jenkins, this bandage was conceived to help burn victims -- especially young ones -- stop infection in its early stages as well as eliminate antiobiotic-resistant strain due to the over prescription of antibiotics in an effort to prevent infection. Unlike most color-changing textiles, the bandage does not rely on climate, heat or moisture to function. Instead it is lined with an outer layer of dye-containing capsules that burst when in contact with toxins in bacteria.
Though the color-changing bandage is still in its conceptual stages, the technology can accurately diagnose wound infections, making a revolution in treatment of serious wounds.
