Researchers at the University of Utah have helped Vaporsens to create a handheld device that can act like a dog’s nose to detect various molecules in the air. The mobile device, which resembles a breathalyzer, is structured with a net of nanofibers that can “sniff out” narcotics and explosives.


The breakthrough technology can assist law enforcement, and public safety officials to detect substances like heroin, methamphetamines, and cocaine. The system can even tell the difference between an explosive element and common interferences like cigarette smoke and gasoline.
