Patent number: 7479329Abstract: 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.Type: GrantFiled: September 26, 2007Date of Patent: January 20, 2009Assignees: University of Massachusetts/Lowell, The United States of America as represented by the Secretary of the ArmyInventors: Susan Tripathy, legal representative, Lynne A. Samuelson, Ferdinando F. Bruno, Sucharita Roy, Ramaswamy Nagarajan, Jayant Kumar, Bon-Cheol Ku, Soo-Hyoung Lee, Sukant Tripathy

Patent number: 7332297Abstract: 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.Type: GrantFiled: March 14, 2003Date of Patent: February 19, 2008Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Lynne A.

Patent number: 7056675Abstract: 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.Type: GrantFiled: October 5, 2004Date of Patent: June 6, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Lynne A.
