The invention provides methods and kits for detecting nucleic acids. The methods employ particles and substrates having oligonucleotides attached to them. The presence of a nucleic acid produces a detectable change such as a , change in color, conductivity or optical density. The invention further provides a method of synthesizing unique nanoparticle-oligonucleotide conjugates, the conjugates produced by the method kits comprising the , conjugates, nanomaterials and nanostructures comprising the conjugates and , methods of using the conjugates.

Why it's free to use
- Filed June 26, 2000 and granted April 19, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 26, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 26, 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.
