- Title
Analytical chemistry: A cheap nose for TNT.
- Abstract
The article discusses the creation of an effective sensing platform for the detection of trace explosives such as TNT. Researchers at Tsinghua University in Beijing and Arizona State University in Tempe have created a device that uses an ionic liquid to pre-concentrate the explosives and electrochemical reactions to generate their reaction products. The products can be absorbed in the visible spectrum in which colorimetric methods are then used to detect them.
