Strong odors are an indicator that food has gone bad, but there could soon be a new way to sniff foul smells earlier on. As reported in ACS Nano, researchers have developed a bioelectronic “nose” that can specifically detect a key decay compound at low levels, enabling people to potentially take action before the stink spreads. It can detect rotting food, as well as be used to help find victims of natural disasters or crimes.
