Surgical adhesives manufactured today have proven their effectiveness. Wound healing with their help is faster, there are almost no complications. Scientists at the University of Sydney and American researchers have jointly created a new product called MeTro. Once inserted into the wound, it seals it in sixty seconds and then dissolves. Nazima Annabi, an assistant professor, assures that the glue that has appeared in the wound hardens in the concentration of the gel. In fact, it is a mixture of extremely elastic proteins from light-sensitive molecules. Thanks to them, he under the influence of ultraviolet rays manages to fix in a wound in a minute. At the same time, the closest connection of tissue surfaces and glue is created without compromising the elasticity of the patient’s tissues. The product contains special enzymes that determine how long it will remain in the wound: from several hours to many months. MeTro, being extremely flexible, is excellent for treating intracavitary wounds, that is, where body fluids are serious destroyers. Scientists are already planning to begin testing in humans, experiments on rodents and pigs, in particular, on the lungs and arteries, have shown remarkable results.
