Open the CIPO recordAbstract From the Canadian patent
The present invention relates to a biomimetic sensor for detecting the presence of airborne toxins, such as carbon monoxide mercury, ethylene oxide, volatile organic materials and hydrogen sulfide. The , biomimetic sensor which has a functional life, of at least one year comprises a porous, semi-transparent substrate into which is impregnated a self-regenerating chemical sensor reagent. The response of the biomimetic sensor mimics the human response to such toxins, with respect to sensitivity and affinity. The extended functional lifetime of the biomimetic sensor and the mimicking of the human response to the toxins are achieved by the use of a molecular encapsulant that encapsulates at …

Why it's free to use
- Filed June 21, 1991 and granted September 14, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 21, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 21, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
