Infections to wounds, such as burns, among children often turn fatal very quickly. Now researchers at University of Bath have developed a new medical dressing that 'lights up' when the burn wound becomes infected.
The dressing is still in a prototype stage and was featured on BBC science show Bang Goes the Theory. The dressing glows under UV light if the wound is infected, thereby providing doctors with a fast diagnosis which can potentially save the lives of the victims.
The dressing contains nanocapsules which are filled up with a dye and which burst open when it comes in contact with disease-causing bacteria. The doctors can then use UV light to check the presence of such bacteria.
