US Patent 7573186 - CNT electrochemical sensor

This patent from Fuji Xerox teaches a variation of a carbon nanotube chemical sensor which purportedly produces higher sensitivity. Claim 1 reads:

1. An electrode for electrochemical measurement comprising:

a plurality of carbon nanotubes,

a catalyst causing a specific chemical reaction, and

an insulator in which the carbon nanotubes and the catalyst are embedded,

wherein the carbon nanotubes are electrically connected with each other by chemical bonding to thereby form a network structure, a part of the catalyst is exposed at a surface of the insulator, and a part of the plurality of the carbon nanotubes are exposed at the surface of the insulator to form an electroconductive portion, and the carbon nanotubes are cross-linked with a cross-linking agent having non-self polymerizability.
