The University of St Andrews and Harvard Medical School have developed a new technique to stimulate healing through fiber-optics. The technique photochemical tissue bonding has been around for a while where light is applied to superficial wounds to help stimulate healing, but it has been unable to treat deeper wounds. The researchers have created a new type of material that is biodegradable so the fiber-optics can be inserted where the wounds are deeper and apply the light to help heal it. Then after the treatment they won't have to worry about removing the fiber-optics and cause the healed tissue damage again.
