Open the CIPO recordAbstract From the Canadian patent
A microelectromechanical system (MEMS) and integrated circuit based biosensor (210) capable of sensing or detecting various ionic molecules and macromolecules (DNA, RNA or protein). The MEMS based biosensor (210) may utilize a hybridization and enzyme amplification scheme and an electrochemical detection scheme for sensitivity improvement and system miniaturization. The biosensor or biosensors (210) are incorporated on a single substrate (200). Preferably, the biosensor system comprises at least two electrodes. The electrodes may comprise a working electrode (220) a reference electrode , (240), and a counter (auxiliary) electrode (230). The biosensor or biosensors (210) also provide …

Why it's free to use
- Filed May 2, 2001 and granted June 7, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 2, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 2, 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.
