Melbourne:Scientists have developed a highly elastic and adhesive surgical glue that can be simply squirted on wounds to seal them within 60 seconds, doing away with the need for stitches. The glue, called MeTro, is ideal for sealing wounds in body tissues that continually expand and relax - such as lungs, hearts and arteries - that are otherwise at risk of re-opening.
The material, developed by researchers at University of Sydney in Australia and Harvard University in the US, also works on internal wounds that are often in hard-to-reach areas and have typically required staples or sutures due to surrounding body fluid hampering the effectiveness of other sealants. MeTro sets in just 60 seconds once treated with UV light, and the technology has a built-in degrading enzyme which can be modified to determine how long the sealant lasts - from hours to months, in order to allow adequate time for the wound to heal.
The liquid or gel-like material has quickly and successfully sealed incisions in the arteries and lungs of rodents and the lungs of pigs, without the need for sutures and staples. MeTro combines the natural elastic protein technologies with light sensitive molecules.
