  • Colorimetric analysis of creatinine in whole blood and urine in a novel paper/polycaprolactone microfluidic device

    Creator:
    Pommerenck, Joel, Heist, Christopher A., and Remcho, Vincent T.
    Abstract:
    A novel approach for the colorimetric detection of creatinine in a paper/polycaprolactone hybrid microfluidic device using alkaline3,5-dinitrobenzoate (DNB) is described. The reaction parameters of reagent concentration, alkalinity, and analysis time are optimized for fast reaction times and high color yield. Microfluidic devices incorporating this assay are designed and fabricated to...

  • Lead(II) Extraction with Electrospun Spiropyran Functionalized PMMA Nanofibers

    Creator:
    Fuchs, Brian K.
    Abstract:
    A system to reversibly extract Pb²⁺ ions from aqueous solutions using spiropyran functionalized nanofibers was proposed. Spiropyrans are photochromic compounds which undergo a conformational change that alters their physical properties and makes Pb²⁺ binding possible upon irradiation with UV light (365 nm). Irradiation with green light (525 nm) reverses this...

  • Restoring and Updating the Micralyne μTK

    Creator:
    Wong, Derek H.
    Abstract:
    The Micralyne microfluidic toolkit (μTK) was an instrument built by Micralyne in the early 2000’s. It was built for electrophoresis and has a sensitive laser-induced fluorescence detection system. The updates to the system were upgrading the control GUI from running in LabVIEW 5 (Windows XP, 2000) to LabVIEW 2012 (Windows...

  • Photoactuated Droplet Microfluidics

    Creator:
    Frederick, Ryan T.
    Abstract:
    A system of Photoactuated Droplet Microfluidics (PDM), in which a droplet of fluid is moved by way of the manipulation of the wettability of a spiropyran functionalized surface via irradiation with ultraviolet and visible light, was proposed. The photochromic behaviors of several species of spiropyran were studied and a procedure...

  • Design and Fabrication of a Polymeric Microfluidic Device for Automated

    Creator:
    Warner, Kelsie E.
    Abstract:
    Gene synthesis is an important tool in molecular biology. However, the current bench-top method of gene synthesis is a costly, time-intensive and reagent-consuming process. Lab-on-chip technology has many benefits over current bench top methods. Microchips consume smaller reagent volumes, are reusable and less expensive to make. This thesis explores the...

  • Comparative Studies of Batch and Continuous Processes for the Synthesis of Copper Nanoparticles

    Creator:
    Ramsing, Patrick E.
    Abstract:
    The cross over from batch nanoparticle synthesis to continuous synthesis processes is crucial to the commercialization of these materials. This project reports comparative studies of batch and continuous synthese of copper nanoparticles by the polyol method. Continuous synthesis of copper nanoparticles was done utilizing a stainless steel micro-mixer that yielded...

    Abstract:
    An estimated total of 30.3 million people have diabetes in the United States, a disease characterized by chronic elevation in blood glucose which over time, can lead to a host of health problems. Currently the most common types of diabetes are type 1, type 2, and gestational. The principal hormone...

  • Engineering Oriented Protein-Labelled Surfaces

    Creator:
    Brown, Wesley and Mehl, Ryan
    Abstract:
    Current protein immobilization techniques lack defined control over protein orientation. Protein orientation is important for making biosensors and biomaterials that are sensitive and efficient and can be crucial for designing some devices such as immunosensors or direct electron transferring biocells. A new method of protein immobilization is proposed that takes...

    Creator:
    Casey, Jorie L.
    Abstract:
    Marijuana (MJ) is a widely used illicit substance among adolescents and young adults. Frequent MJ use has been associated with impairments in cognitive flexibility and inhibition, both of which play important roles in decision-making. However, the impact of frequent MJ on decision-making performance is mixed and not well understood. The...

  • Evaluation of Oxidation Reduction Potential in Metabolic Syndrome Subjects Compared with Matched Normal Subjects

    Creator:
    Cobb, Tora Jean
    Abstract:
    This study was conducted to assess whether healthy adults compared with those with Metabolic Syndrome (MetS) have different mean oxidative-reductive potentials. Static oxidation-reduction potentials and capacity oxidation reduction potentials (sORP and cORP, respectively) were measured in plasma samples. The RedoxSYS® measures sORP in millivolts (mV), which is proportional to the...
