The present invention is directed to a method of producing a substrate suitable for separation of a target molecule from a fluid medium. This method includes providing an emulsion comprising a water phase in an oil phase where , the oil phase contains a polymerizable monomer and the water phase contains the target molecule. The substrate, having pores extending from one side of the substrate to another side of the substrate is coated with the emulsion, and the monomer in the emulsion coated substrate is then polymerized. The water and target molecule are removed from the polymerized emulsion coated , substrate. As a result the substrate is imprinted with the target molecule and, …

Why it's free to use
- Filed August 13, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 13, 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.
