Cotton candy-like material used to heal difficult wounds

Many diabetics suffer from a condition known as venous stasis, which can result in wounds on their extremities that remain unhealed for up to several years – if infection sets in, amputation of the limb is sometimes even necessary. Such wounds can sometimes be treated with vacuum-assisted systems, but the equipment required is expensive, and must be carried by the patient at all times. In clinical trials conducted last year, however, human venous stasis wounds were quickly and thoroughly healed with an inexpensive new glass nanofiber material, that looks like cotton candy.
