Bytesize Science: The e-Nose: Scientists try to develop an electronic sniffer

In our second video podcast, we find out that scientists are sniffing around for a way to develop an electronic nose. For almost 25 years, chemists and other scientists have tried to build a machine that can take a whiff of the air, food or other objects and say whether the odor is nasty or nice. Such a machine could work in factories, and help tell whether food is fresh. An electronic nose also could sniff for harmful air pollutants. And unlike people, it could work 24 hours a day and 7 days a week without getting tired.
