Gas Sensor Technology |
YTCA has fabricated prototype gas sensors utilizing its proprietary hybrid CNT materials, in which various metal dopants are incorporated into the CNT bundles:

Some of these materials have shown enhanced sensitivity to analyte gases such as nitrogen dioxide (NO2), as shown below:
