Commercialized CNT gas sensors
-
The final goal of these efforts is toward the development of
commercial devices based on gas-sensitive CNT layers. These
commercial chemical sensors are not yet developed, and it is
expected that within -5-10 years they will appear in the market
with high performance and low cost.
We can speculate at high degree of confidentiality that CNTs will
be one of the most important building blocks at the nanoscale for
future sensing devices:
•
Field-effect transistors
: Innovative transistors at high freq-
uency based on purified, modified and functionalized
SWCNTs, at format of individual nanotube or networked
bundles, will provide unprecedented chemical sensitivity.
