Toward a Test Strip for Detecting TNT and Other Explosives in Water

Professor Yu Lei and Ph.D. student Ying Wang describe the development of a new explosives detector that can sense small amounts of TNT and other common explosives in liquids instantly with a sensitivity that rivals bomb-sniffing dogs, the current gold standard in protecting the public from terrorist bombs. They report on the technology at the 243rd National Meeting & Exposition of the American Chemical Society (ACS). Watch the video.
