  • POLYMER AND METHOD OF USE
    Publication number: 20150361203
    Abstract: A polymer is imprinted with an agricultural chemical molecule having a heterocyclic ring, wherein the matrix of said polymer has been prepared from one or more monomers including bilirubin or a mono-or di-ester or amide thereof, and wherein the heterocyclic ring has 1-3 nitrogen atoms. The imprinted polymer is useful for removing agricultural chemicals from liquids including waste water, drinks and food ingredients.

  • Imprinted polymer for binding of organic molecules or metal ions
    Publication number: 20090191644
    Abstract: The invention relates to an imprinted polymer imprinted with an organic molecule or a metal ion wherein the matrix of the polymer has been prepared from one or more monomers including bilirubin or an analogue thereof. The imprinted polymers may be prepared by polymerising one or more monomers including bilirubin or an analogue or derivative thereof in the presence of the molecule or metal ion to be imprinted or an analogue or derivative thereof, and subsequently at least partly removing the molecule or ion to be imprinted or its analogue or derivative. The polymers may be used in a method for detection and/or assay of the imprinting molecule or metal ion.

  • Polymers for binding of phenols
    Patent number: 7229836
    Abstract: The invention relates to a method for the detection and/or measurement of a phenol comprising: (a) contacting the sample to be tested with a polymer imprinted with the phenol or an analogue thereof; and (b) measuring binding of the phenol to the polymer. The polymer may be prepared by polymerizing a polymerizable monomer, to which a phenol is covalently bound by a hydrolysable linker, and subsequently removing the phenol by hydrolysis. Propofol is a preferred phenol for use in the invention.
