New research may help in the fight against terrorism with the creation of a sensor that can detect tiny quantities of explosives with the use of light and special glass fibers. The researchers describe a novel optical fiber sensor which can detect explosives in concentrations as low as 6.3 ppm (parts per million). It requires an analysis time of only a few minutes.
