  • Patent number: 7915318
    Abstract: A water soluble ROMP catalyst, which has high catalytic efficiency for ring opening metathesis is use in the preparation of polymeric blends for use in monolithic columns. In one embodiments a method for making a polymeric blend is discolosed comprising reaction of a water-soluble ROMP catalyst with a norbornene-substituted cycloolefin polymer or a polynorbornene polymer precursor, and wherein the contacting occurs in an aqueous or polar solvent in the presence of a solid support. In another embodiment a monolithic bed is disclosed comprising the water-soluble ROMP catalyst immobilized on a surface of a solid support. Also disclosed is a monolithic bed comprising: a polymer blend, the polymer blend produced from contacting a water soluble ROMP catalyst with a norbornene-substituted cycloolefin polymer or a polynorbornene polymer precursor; and wherein the contacting occurs in an aqueous or polar solvent in the presence of a solid support.

  • Publication number: 20100015633
    Abstract: A method includes binding a probe to an analyte present in a sample, wherein the probe comprises a binder bonded to a metal particle that is capable of releasing metal ions when contacted with a reagent solution. The method includes contacting the metal particle with the reagent solution to release the metal ions, and observing an optical signal from the released metal ions to determine a presence or amount of the analyte in the sample. An associated kit is also provided.
