Bandaged wounds need to be checked for infection, yet removing the bandage to check the wound can delay its healing. Australian scientists may have a fix for this paradox, in the form of a dressing that glows if the wound is infected.
Currently being developed at RMIT University, the material incorporates nanosheets of magnesium hydroxide that are embedded onto the nanofibers of a standard cotton bandage. Once applied to a wound – particularly a chronic wound, such as a diabetic ulcer – the biocompatible magnesium hydroxide proceeds to help in the healing process by killing harmful bacteria and reducing inflammation.
