A microsphere-based analytic chemistry system and method for making the same is disclosed , in which microspheres or particles carrying bioactive agents may be combined randomly or in ordered , fashion and dispersed on a substrate to form an array while maintaining the ability to identify the, location of bioactive agents and particles within the array using an optically interrogatable, optical , signature encoding scheme. A wide variety of modified substrates may be employed which provide , either discrete or non-discrete sites for accomodating the microspheres in either random or patterned , distributions. The substrates may be constructed from a variety of materials to form either …

Why it's free to use
- Filed September 10, 1999 and granted November 22, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 10, 2019.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
