In this interview Dr. Ifor Samuel from the Organic Semiconductor Centre at the University of St. Andrews, discusses his research team's recent AIP Advances article, Ultra-portable explosives sensor based on a CMOS florescence lifetime analysis micro-system. The research presents the construction of an ultra-portable device that effectively detects explosives by using the change in a fluorescent polymer's light-emitting power to detect explosive vapors. The Scottish team's prototype is the first to use a compact silicon-based micro-system to measure the change in the length of time an electron stays in the excited higher energy state. This measurement is less affected by environmental factors, such as stray light, which should make the device more reliable. Future work may soon see it helping to reclaim landmine-littered land.
