Bandage to stops bleeding in an instant

    A new nanoscale bandage will use a natural clotting agent found in blood to stop bleeding in an instant.
    The bandage will be developed by coating the clotting agent thrombin onto sponges that will be fitted to just about any wound. Spraying the sponges with a biological nanoscale coating containing layers of tannic acid and thrombin will create a film capable of being stored and easily carried. The sponges will be particularly useful for stopping bleeding at the neck, a situation not suitable for tourniquets.
