They examined the wound dressings in diabetic mice, which can be a repeatedly used style for human wound therapeutic.
“We discovered that {the electrical} stimulation from the tool speeded up the speed of wound closure, promoted new blood vessel formation, and diminished irritation—all of which level to total progressed wound therapeutic,” reported co-first writer Maggie Jakus, a graduate pupil at Columbia College.

The mice who gained remedy with WPEDs healed about 30% quicker than mice who gained standard bandages.
