Open the CIPO recordAbstract From the Canadian patent
In a recognition complex system, nucleic acid ligands comprising random DNA sequences are operatively coupled to an organic semiconductor and distributed so as to form an array of recognition complexes. When an unknown chemical or biological analyte is applied to the array the electrical and/or , photochemical properties of one or more of the recognition complexes are altered upon binding of the nucleic acid ligand to the analyte. The degree to which the electrical and/or photochemical properties change is a function of the affinity of the nucleic acid ligand sequence for the analyte. The electrical and photochemical changes associated with the array as a whole, can be used as a …

Why it's free to use
- Filed June 30, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 30, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 30, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
