Scientists working on e-nose to rival the keenest bloodhound

Abstract:
The key is a curious combination of the latest space-age material with a biological substance almost as old as life itself: carbon nanotubes coated with a thin layer of animal DNA. The nanotubes serve as miniature transistors, and are hooked up to tiny electrodes and fed with current. When particles to be "smelled" bond with the DNA, that somehow affects the amount of current flowing through the underlying nanotubes, but in ways that are not fully understood.
