"Successful convictions in the fight against rising gun crime could be given a boost thanks to new DNA tagging technology developed by scientists at the University of Surrey. The breakthrough uses nanotechnology to coat gun cartridges which captures the user’s DNA. These ‘nanotags’ are also easily transferred to the user’s hands and clothing and are difficult to wash off, making it harder for gun criminals to cover their tracks."
