Scientist have recently discovered a new technology to catch criminals, this technology enables the people to see the fingerprints left by the criminal even after the criminal wiped a away the evidence. Now villains are easier to catch! Usually the finger leaves behind sweat and natural oil that trace the lines of the fingertips, Amazing right? The way that they do this is using colour-changing fluorescent films that helps to capture latent or hidden prints on knives, guns, bullet casings and more!
