  • Field-use electrochemical sensors for detection of carbamazepine in saliva and water

    Creator:
    Minzlaff, Jade
    Abstract:
    The anticonvulsant drug carbamazepine (CBZ) is a commonly prescribed drug that is used to treat patients with neurological disorders including epilepsy and bi-polar disorder. CBZ has a narrow range of efficacy: Below the therapeutic dose, seizures and other conditions are not controlled, and above the recommended window, patients experience side...

  • Reversible Covalent Immobilization of Desferrioxamine B (DFOB) on Aminated Polystyrene Beads for Citrate-Bound Fe(III) Chelation

    Creator:
    Touma, Jad G.
    Abstract:
    The immobilization of chelators to solid supports has recently gained renewed interest due to the increasing biomedical and environmental applications made possible by these molecules’ ability to bind Fe(III) and other metal ions. The uses of immobilized chelators have expanded to include the treatment of metal overload in serum, the...

  • Catalytic chemical vapor deposition synthesis of carbon nanotubes from methane on SiO supported Fe and Fe−Ni catalysts

    Creator:
    Nakagawa, Ayako
    Abstract:
    Influences of operating conditions on the production of carbon nanotubes (CNTs) were studied using Fe and Fe-Ni bimetallic catalysts supported on silicon monoxide (SiO). The catalysts were prepared in three steps: (1) impregnation of SiO powders with ferric nitride or combinations of ferric and nickel nitrides, (2) oxidation of nitrides...

  • Processing of nanoscale materials

    Creator:
    Hostetler, Eric B.
    Abstract:
    The motivation for undertaking this research was to increase the understanding of processing colloidal semiconductor nanocrystals and thin films metallic glasses to enable their wider application in future devices. This research covered two unique materials, lead selenide (PbSe) nanocrystals and thin film metallic glass alloy of zirconium copper aluminum nickel...

  • Applications of Nonthermal Microplasmas in Chemical Reaction Engineering

    Creator:
    Kreider, Peter B.
    Abstract:
    Nonthermal plasmas generate high concentrations of excited species that can simultaneously exist at high energy and far from thermodynamic equilibrium, making them useful tools in chemistry and engineering. Microplasmas, roughly defined as plasmas that are generated within sub-millimeter dimensions, provide enhanced stability, improved excited species density, increased nonequilibrium properties, higher...

  • Effect of cosputtered catalyst on growth and alignment of carbon nanotubes by plasma enhanced chemical vapor deposition

    Creator:
    Gunderson, Eric P.
    Abstract:
    The effect of cosputtered catalyst on growth and alignment of carbon nanotubes (CNTs) grown by plasma enhanced chemical vapor deposition (PECVD) was investigated. Aligned CNTs were observed using a cosputtered catalytic metal deposited directly on boro-aluminosilicate glass. Catalytic metal alloys were sputtered directly onto the substrate using magnetron sputtering. Deposition...

  • Device Fabrication and Characterization for Biological and Radiation Sensing

    Creator:
    John, Stebby Varghese
    Abstract:
    Amorphous indium gallium zinc oxide (IGZO) thin film transistors (TFT) has revolutionized the display industry enabling smaller pixel sizes and higher refreshing rates than traditional amorphous Si: H TFTs. These attributes of IGZO were leveraged to make a field-effect sensing (FES) platform capable of sensing various biomarkers. The sensitivity and...

  • Biomolecule detection by amplified photoluminescence of germanium doped diatom biosilica

    Creator:
    Gale, Debra K.
    Abstract:
    There is significant interest in the fabrication of nano- and micro-structured silica with spatially ordered features, which exhibit enhanced optoelectronic properties with application to the next generation of display devices, semiconductors, and sensors. Currents methods of fabrication employ top down processes which use extremes of temperature, pressure, and power. There...

  • 2,4,6-trinitrotoluene detection using photoluminescence response of diatom biosilica functionalized with single-chain variable fragment

    Creator:
    Zhen, Le
    Abstract:
    A label-free, photoluminescence (PL) based biosensor for 2,4,6-trinitrotoluene (TNT) detection was developed by functionalizing diatom biosiilica with a TNT-specific single-chain variable fragment (scFv). The scFv loading was estimated to be 0.040±0.003 (μg scFv/μg biosilica). In saturated concentration, TNT binding to scFvbiosilica quenched about 13% of its PL. Dose response follows...

  • Solution-based deposition of functional thin films : development of a glucose biosensor and thermal processing of CZTS nanoparticle films

    Creator:
    Durgan, Christopher J.
    Abstract:
    The development of solution-based methods for deposition of different thin film material is presented as an alternative to high cost vacuum-based methods. For certain materials, vacuum techniques are unsuitable for processing. Additionally, vacuum-based processes present high capital costs associated with equipment, and slow processing times. Atmospheric pressure solution based techniques...
