US Patent 7155959 - Nanodisk Sensor

Nanoink is a company which is commercializing technology based on dip pen nanolithography which basically uses a nanoscopic tip to directly write patterns on a substrate. This patent employs dip pen techniques to form gas sensors on the nanoscale which may possess greater sensitivity than conventional sensors. Claim 1 reads:

1. A sensor for temperature and gas detection comprising a sol gel nanodisk fabricated between conducting electrodes whereby the sol gel nanodisk comprises a semi-crystallized structure having surface oxygen ions.
