Glowing report for TNT

A fluorescent gel added to filter paper could make a quick and easy detector for the explosive trinitrotoluene, TNT, according to a team led by Ayyappanpillai Ajayaghosh of the National Institute for Interdisciplinary Science and Technology in Trivandrum, India. The approach which uses OPVPF, a perfluoroarene based gelator known to form arene-perfluoroarene, could be a less costly alternative to ion mobility spectroscopy detection or sniffer dogs in certain security-conscious settings.
