  • A comparative study of fish coloration and toxicant responses in a chromatophore cell-based biosensor

    Creator:
    Roach, Holly B.
    Abstract:
    Detection of both biological and chemical environmental toxicants is essential in the assessment of risk to human health. Cell-based biosensors are capable of activity- based detection of toxicity. Chromatophore cells, responsible for the pigmentation of poikilothermic animal, have shown immense potential as cell-based biosensors in the detection of a broad...

  • The role of Salmonella typhimurium type three secretion system (T3SS) and effector proteins in chromatophore cell response.

    Creator:
    Farhad, Mohammad
    Abstract:
    Bacterial contamination of food poses a great risk to human health worldwide. A chromatophore cell-based biosensor, utilizing B. splendens erythrophore cells, is an emerging technology that has shown potential to detect bacterial toxicity based on function-dependent mechanisms. Previous studies have investigated the response of erythrophore cells to foodborne pathogens, pesticides,...

  • The design and development of the wearable health and activity monitor

    Creator:
    Glover, Neil E.
    Abstract:
    This work describes the development of an accurate, low-cost, expandable and wearable health and activity monitoring platform. Wearable monitors used to track physical activity are becoming an increasingly popular and effective way to combat our dangerously sedentary lifestyles. Unfortunately most existing wearable solutions are either costly, inaccurate or cumbersome. The...

  • Passive health monitoring with wirelessly powered medical devices

    Creator:
    House, Samuel
    Abstract:
    The proliferation of body worn autometric devices has been enabled by advances in low-power electronics and fueled by the quantified-self movement. These devices range in complexity from pedometers to clinical vital sign measurement. They all share the same drawback, typically the most expensive and heaviest component, the battery. The future...

  • Analysis and design on low-power short-range radios for wireless body area networks

    Creator:
    Cheng, Jiao
    Abstract:
    The release of the IEEE802.15.6 standard has led to increased interest in low-power technologies for wireless body-area-networks (WBANs). The power dissipation, supply voltage, and die area are some of the most important criteria for successful WBAN implementations. Digital-intensive RX architectures can potentially result in sub-1V operation with significant reductions in...

  • Bacterial pathogens and associated toxins involved in erythrophore cell aggregation

    Creator:
    Hutchison, Janine R.
    Abstract:
    Current detection methods for bacterial contamination rely on structure based detection of proteins and nucleic acids. While these methods are easy to use and reliable, they cannot evaluate the toxicity of a sample and the potential to cause disease. Previously, erythrophore cells derived from Betta splendens had been suggested as...

  • Comparison of carbon nanotube and graphene field-effect transistor biosensors

    Creator:
    Saltzgaber, Grant William
    Abstract:
    Detection of biomolecules is important for the diagnosis and treatment of diseases. Low concentration detection, specific biomolecule detection, and point-of-care use are appealing characteristics for biosensors because of the possibility of early detection and quick results of specific biomolecules. Furthermore, inexpensive biosensors are appealing so that they are accessible to...

  • Analysis of Betta splendens erythrophore responses to Bacillus cereus cultured in different media

    Creator:
    Austin, Melissa J.
    Abstract:
    Biological agents and their products commonly cause foodborne illnesses. In the United States it is estimated that there are over 76 million cases of foodborne illnesses each year, resulting in an economic loss of approximately $40 billion. These high figures demonstrate the need for bioassays that display a rapid and...
