'Nano-flowers' show promise for alcohol detection

Abstract:
Spectacular flower-like nanostructures grown in a laboratory in China can detect alcohol and might also be useful as catalysts.

The "nanoflowers" were made from zinc oxide by Yujin Chen and colleagues at Harbin Engineering University. Conventional ethanol sensors are made from the same material and work by detecting the change in electrical resistance when a wad of zinc oxide powder or a layer of the material is exposed to ethanol vapour.
