Open the CIPO recordAbstract From the Canadian patent
A semiconductor device (Figure 1) is provided for the detection of nitric oxide (NO) molecules in gaseous mixtures in biological fluids and in aqueous , solutions. The device is a molecular controlled semiconductor resistor (MOCSER) of a multilayered GaAs structure to which top layer a layer of multifunctional NO-binding molecules are adsorbed. The sensitivity of the semiconductor device towards NO is independent of mixture composition. Nitric oxide concentrations of as low as 10 ppb NO were detected in mixtures containing various contaminants.

Why it's free to use
- Filed January 17, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 17, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 17, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
