In Brief A new method of closing wounds has been discovered by researchers from University of St. Andrews and Harvard Medical School. In the future, your wounds might not be closed by stitches or staples.
Rose Bengal Dye, a common dye used by optometrists, can be used in tandem with a laser to suture wounds; however, notably, the dye will only go as deep as the laser does, which makes it somewhat less than effective for wounds that penetrate many layers of skin, but it does eliminate the need for staples and traditional sutures or stitching in relation to a number of different injuries.
In short, the solution can be used as a kind of “Biological guide;” it effectively directs the light into the wound, causing a nice, even suture.
As was previously mentioned, currently, the procedure is only applicable for superficial, shallow wounds, which means that scarring probably won’t be much of a concern for the wounds that it can be used on anyways.
Researchers were able to test the wave guide by closing a 10 millimeter deep wound on pig skin.
With further study, they hope to pave the way for “Photo-medicine” to heal deeper wounds.
