  • Publication number: 20070021587
    Abstract: Hematin, a hydroxyferriprotoporphyrin, is derivatized with one or more non-proteinaceous amphipathic groups. The derivatized hematin can serve as a mimic of horseradish peroxidase in polymerizing aromatic monomers, such as aromatic compounds. These derivatized hematins can also be used as catalysts in polymerizing aromatic monomers, and can exhibit significantly greater catalytic activity than underivatized hematin in acidic solutions. In one embodiment, polymerization is in the presence of a template, along which aromatic monomers align. An assembled hematin includes alternating layers of hematin and a polyelectrolyte, which are deposited on an electrically charged substrate. Assembled hematin can also be used to polymerize aromatic monomers.

  • Patent number: 7109136
    Abstract: A conductive (electrical, ionic, and photoelectric) polymer membrane article, comprising a non-woven membrane of polymer fibers, wherein at least some of the fibers have diameters of less than one micron; and wherein the membrane has an electrical conductivity of at least about 10?6 S/cm. Also disclosed is the method of making such an article, comprising electrostatically spinning a spin dope comprising a polymer carrier and/or a conductive polymer or conductive nanoparticles, to provide inherent conductivity in the article.

  • Patent number: 7056675
    Abstract: A conductive polymer is formed enzymatically in the presence of a polynucleotide template. The method includes combining at least one redox monomer with a polynucleotide template and a redox enzyme, such as horseradish peroxidase, to form a reaction mixture. The monomer aligns along the template before or during the polymerization. Therefore, the polynucleotide template thereby affects the molecular weight and conformation of the conductive polymer. When the conductive polymer is complexed to a polynucleotide duplex, the conformation of the polynucleotide duplex can be modulated by changing the oxidation state of the conductive polymer.

  • Publication number: 20060078756
    Abstract: An assembled hematin is formed by depositing hematin on an electrically charged substrate in one or more layers alternating with one or more layers of polyelectrolyte, preferably a cationic polymer. In a method for polymerizing an aromatic monomer, the assembled hematin is contacted with the monomer and a template, preferably an anionic polymer. In a method for polymerizing aniline, the aniline, sulfonated multi walled carbon nano tubes, PEG hematin and a reaction initiator are dispersed in water.
