Florescence is used to detect finger prints

In many crime scenes the finger prints are sometimes hard to see. But scientist have figures out a way in which  a finger print becomes florescent  and much easier to see. They did have a way to make it florescent before but it was very dangerous and it needed to be done in fume cupboards. But scientist have come across that hurdle. Scientist from Laboratoire de Photophysique et Photochimie Supramoléculaire et Macromoléculaire (CNRS/ENS Cachan), in partnership with the specialized firm Crime Scene Technology where able to combine cyanoacrylate with Tetrazine and then it would be put onto the fingerprint, then using uv light the finger print would be more visible and police officers would be able to take photographs. It requires less cost and time which is good. That is cool that they where able to come up with a way to do that.
