MIT uses nanotubes to sense deadly gases
An optical image of the interdigitated gold electrodes upon which the carbon nanotubes are deposited. Bottom: A scanning electron microscopy image of the gold electrodes (thick gray bars). The carbon nanotubes are the small string-like wires extending into the black regions between the electrodes.
Using carbon nanotubes, MIT chemical engineers have built the most sensitive electronic detector yet for sensing deadly gases such as the nerve agent sarin.
