Novel Explosive Detection System Petri Dish Test

Caption: University of Connecticut scientists have developed a novel buried explosive detection system using a nanofiberous film and ultraviolet light. Image, top, shows a Petri dish (left) with buried trace levels of 2,4-DNT explosive in soil and a Petri dish (right) without DNT. Image, bottom, shows each Petri dish after application of the chemical sensing film and following 30 minutes exposure under ultraviolet light. The location of the buried DNT appears in the Petri dish (left) as a dark blot on the film.
