Patent number: 9005540Abstract: Hollow conjugated polyelectrolyte (HCPE) microcapsules contain at least one conjugated polyelectrolyte and at least one other polyelectrolyte of complementary charge and the microcapsule has a hollow core. The conjugated polyelectrolyte is a polymer with a multiplicity of charged repeating units where a portion of the charged repeating units form a pi-conjugated sequence. The complementary polyelectrolyte is a polymer with a complementary charged repeating unit to the charged repeating units of the conjugated polyelectrolyte. The HCPE microcapsules can be formed by successively coating a sacrificial core with alternating layers of complementary polyelectrolytes, at least one of which is a conjugated polyelectrolyte. The sacrificial core can be removed to form the hollow center of a HCPE microcapsule.Type: GrantFiled: November 27, 2013Date of Patent: April 14, 2015Assignees: University of Florida Research Foundation, Inc., STC.UNMInventors: Kirk S. Schanze, Motokatsu Ogawa, Jonathan Robert Sommer, David G. Whitten, Thomas S. Corbitt

Patent number: 8753570Abstract: Novel compounds generally referred to herein as cationic oligomeric phenylene ethynylenes (OPEs), methods of synthesizing OPEs and various uses for the OPEs are described. The compounds can be synthesized in both symmetrical (S-OPE) and non-symmetrical (N-OPE) forms. Suitable uses include sensor and biocidal applications. Reusable structures incorporating the OPEs that are able to capture and release biological species of interest are also described.Type: GrantFiled: June 26, 2009Date of Patent: June 17, 2014Assignee: STC.UNMInventors: David Whitten, Yanli Tang, Zhijun Zhou, Linnea Ista, Motokatsu Ogawa, David Keller, Brett Andrzejewski, Gabriel Lopez, Kirk Schanze

Patent number: 8455265Abstract: A surface grafted conjugated polyelectrolyte (CPE) is formed by coupling a CPE by a coupling moiety to the surface of a substrate. The substrate can be of any shape and size, and for many uses of the surface grafted CPE, it is advantageous that the substrate is a nanoparticle or microparticle. Surface grafted CPEs are presented that use silica particles as the substrate, where a modified silane coupling agent connects the surface to the CPE by a series of covalent bonds. Two methods of preparing the surface grafted CPEs are presented. One method involves the inclusion of the surface being modified by the coupling agent and condensed with monomers that form the CPE in a grafted state to the substrate. A second method involves the formation of a CPE with terminal groups that are complimentary to functionality that has been placed on the surface of the substrate by reaction with a coupling agent. The surface grafted CPEs are also described for use as biosensors and biocides.Type: GrantFiled: February 29, 2008Date of Patent: June 4, 2013Assignee: STC.UNMInventors: David G. Whitten, Sireesha Chemburu, Thomas Corbitt, Linnea Ista, Gabriel Lopez, Kirk S. Schanze, Motokatsu Ogawa, Eunkyung Ji
