In a journal article in Nature Materials, MIT researchers explained how they have helped turn spinach plants into “bomb sniffing machines.” The plants were embedded with tiny carbon tubes to help them detect “nitroaromatics” (chemical compounds used in explosives). Once the plant detects the compound in the air, it emits a fluorescent signal that is picked up by an infrared camera and wirelessly notifies a smartphone.
