More sensitive than a dog's nose and the sensors don't get tired

Researchers are harnessing next-generation photovoltaics materials to create a fast, accurate testing mechanism for harmful compounds

Researchers will develop a system to trace the source of dust on suspect articles to match a soil profile of a specific area or overseas country

The method uses infrared light spectroscopy and can be used in a portable, tabletop device

Early career researcher develops new library for faster, accurate detection of deadly toxins

New device is able to detect trace amounts of nitroaromatic compounds and can be applied to identify the majority of explosives or highly toxic pollutants for medical and forensic evaluations

New analytical tool could aid human rights, public safety workers

A new way to inspect cargo at ports of entry

The new detection method is able to analyze a wider range of materials than current thermal based detection systems used in today’s airports, while reducing false positive reports

New device can detect gamma rays and identify radioactive isotopes
