Near infrared (NIR) spectroscopy could be used to detect hazardous chemicals hidden behind clothing, and could improve security screening technology in places such as airports.
Celine Canal, David Hutchins and colleagues from the University of Warwick detected the explosive ammonium nitrate hidden behind a layer of various clothing materials, from light acrylic to thick denim. ‘Light in the NIR wavelength range is invisible to the naked eye, allowing unnoticeable remote detection,’ explains Hutchins.
