Open the CIPO recordAbstract From the Canadian patent
A method detects binding of molecules, advantageously without tagging molecules in the sample. A sensor is used in which is included a single stranded nucleic acid sequence and a photoluminescent material in respective layers. After the sensor is exposed to a biological sample for sufficient time for its single stranded nucleic acid sequence to bind to a material of interest, photoluminescence from the sensor can be measured. An apparatus for tagging-free detection of binding of molecules also is provided. Methods of making tagging-free sensors are provided. Also tagging-free methods to detect , binding of antigens and related devices are disclosed.

Why it's free to use
- Filed October 1, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 1, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 1, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
