  • Publication number: 20060041110
    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: 20040198945
    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.

  • Publication number: 20040023346
    Abstract: The invention relates to a novel method for enzymatic polymerization which includes (1) obtaining a reaction mixture including a monomer, a template, and an enzyme; and (2) incubating the reaction mixture for a time and under conditions sufficient for the monomer to align along the template and polymerize to form a polymer-template complex. The template can be a micelle, a borate-containing electrolyte, or lignin sulfonate. Such a complex possesses exceptional electrical and optical stability, water solubility, and processibility, and can be used in applications such as light-weight energy storage devices (e.g., rechargeable batteries), electrolytic capacitors, anti-static and anti-corrosive coatings for smart windows, and biological sensors.

  • Patent number: 6569651
    Abstract: The micelle contains multiple units, each of which contains a hydrophobic part and a hydrophilic part. A preferred unit is dodecyl benzene sulfonic acid. Borate-containing electrolytes include trifluoroborate, trimethylborate and hydrobis(pyridine)boron. Enzymes include peroxidases such as horseradish peroxidase or lignin peroxidase, and laccase. Monomers include unsubstituted and substituted anilines and unsubstituted and substituted phenols. A method is provided for enzymatic polymerization which includes (1) obtaining a reaction mixture including a monomer, a template, and an enzyme; and (2) incubating the reaction mixture for a time and under conditions sufficient for the monomer to align along the template and polymerize to form a polymer-template complex. The template can be a micelle, a borate-containing electrolyte, or lignin sulfonate.
