Abstract

See full text

Apparatus for detecting and identifying a chemical species in an environment, the apparatus comprising: a plurality of carbon nanotubes arranged to form a network, the network comprising a plurality of inter-carbon nanotube junctions; a plurality of electrical contacts, each of the plurality of electrical contacts being connected to the network such that the anisotropic electrical characteristics of the network can be measured dynamically while the network is exposed to the environment; wherein the network possesses electrical anisotrophy such that the ratio of the number of inter-carbon nanotube junctions which must be traversed by current per length of the plurality of carbon nanotubes differs for different directions within the network along the path from one of the plurality of electrical contacts to another of the plurality of electrical contacts, and further wherein the electrical anisotrophy of the network changes when a chemical species is present in the environment.
