Open the CIPO recordAbstract From the Canadian patent
Novel nanowell microarrays are disclosed in optical contact with polymer waveguides (58) wherein evanescent field associated with lightwaves propagated in the waveguide (58) excite target substances in the nanowells (57) either by a common waveguide or by individual waveguides. Fluid samples are conveyed to the nanowells (57) by means of microfluidics (21). The presence of the target substances in fluid samples is detected by sensing fluorescent radiation generated by fluorescent tag bound to the target substances. The fluorescent tags generate fluorescent radiation as a result of their excitation by the evanescent field. One or more PMT detectors or a CCD detector (15) are located …

Why it's free to use
- Filed April 30, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 30, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 30, 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.
