Tim Swager, from MIT, is the 2013 winner of the ACS Award for Creative Invention for his work on the world’s most sensitive explosive detector to date. Known as FIDO, the handheld detector has been used to detect roadside bombs in Iraq, as well as homeland security operations and in airport security. It is named FIDO as, much like tradition bomb sniffing dogs, it “sniffs” for bombs. Unlike dogs, the FIDO doesn’t get tired, doesn’t get attached to its trainer and doesn’t need to acclimatize to its location.
