Detection of Explosives: A Colorimetric Artificial Olfactory System for Airborne Improvised Explosive Identification (Adv. Mater. 14/2020)

In article number 1907043, Zhenzhen Cai, Xincun Dou, and co-workers report a colorimetric artificial olfactory system with excellent discrimination capabilities, rapid response, and low detection limit for detecting airborne improvised explosive microparticulates. This work contributes not only to resolving the challenges of improvised explosive detection, but also to making the detection of nonvolatile target analytes possible.
