Spray-on bandages could help protect wounds and deliver life-saving drugs in far-flung places where immediate medical care is not available, according to a new study.Using a technique called electrospinning, scientists created “bottled bandages” which spray a thin layer of fibres onto damaged skin like spraying paint on a wall.
