  • Large-Area Nanoplasmonic Structures for Enhanced Fluorescence-Based Biosensing

    Creator:
    Wang, Yi-Chieh
    Abstract:
    An innovative silver nano-dimple arrays (Ag DAs)-integrated microfluidic device was developed to achieve highly sensitive fluorescence-based nucleic acid detection. The Ag DAs were utilized to produce surface plasmon resonance (SPR) for strong fluorescence enhancement. We systematically investigated the plasmon-enhanced fluorescence by controlling the nanostructure dimension of the Ag DA substrate....

  • Quantum dots-fullerene based molecular beacons for highly sensitive DNA detection

    Creator:
    Liu, Ye
    Abstract:
    We demonstrated a low-cost and high-sensitivity DNA detection method using quantum dot-fullerene based molecular beacons (MBs) and magnetic nanoparticles. The MB tethered magnetic nanoparticles can be well dispersed in analytes for efficient DNA capture and concentrated by an external magnetic field for enhanced fluorescence signal detection. The detection requires only...

  • Refrigerated seawater depuration for reducing Vibrio parahaemolyticus contamination in raw Pacific oysters (Crassostrea gigas)

    Creator:
    Yang, Qianru
    Abstract:
    Vibrio parahaemolyticus is a seafood-borne pathogen that can cause gastroenteritis in humans. This study investigated the effectiveness of refrigerated seawater (5°C) depuration on reducing V. parahaemolyticus in raw Pacific oysters (Crassostrea gigas). Raw Pacific oysters were inoculated with a mixed culture of five clinical strains of V. parahaemolyticus and depurated...

  • Printed Nanocomposite Devices and Flexible Electronics for Humidity Sensing

    Creator:
    Ajithkumar, Amritha
    Abstract:
    The thesis focuses on the development of a novel printed resistive humidity sensor and integrated flexible electronics for an RFID-enabled humidity sensing platform. We explored a hybrid nanocomposite material for humidity sensing consisting of carbon nanomaterials, conductive polymer and cellulose polymer that undergoes resistance change in response to humidity change....

  • Nanostructured Optical Devices for Biosensing Applications

    Creator:
    Chalishazar, Vishvas
    Abstract:
    We demonstrated a sensitive biosensor based on plasmonic metal composite nanostructures. The device can be fabricated and duplicated with ease using a novel nanoprinting technology which allows precise transfer of metal nanostructures without complicated lithography processes. The design featured by its unique material composition and sub-wavelength structures maximizes the exposure...

  • Calculation of axial mode separation of a semiconductor laser from reflectance spectrum

    Creator:
    Thinh, Nguyen Hoang
    Abstract:
    It is reported that the axial mode separation of a semiconductor laser can be computed from the reflectance spectrum of a narrow spectral range near the lasing frequency. The Kramers-Kronig dispersion relation is used in this computation. GaAs semiconductor laser is taken as an example. The computed values of the...

  • Electrolyzed oxidizing water treatment as a post-harvest process for controlling histamine formation in fish

    Creator:
    Phuvasate, Sureerat
    Abstract:
    Scombroid poisoning, caused by histamine intoxication, is one of the most prevalent illnesses associated with seafood consumption in the United States. The illness is usually accompanied with a variety of symptoms, such as rash, nausea, diarrhea, flushing, sweating, and headache. Incidence of scombroid poisoning has been consistently reported in the...

  • Application of Antimicrobial Substance in Depuration for Decreasing Vibrio Parahaemolyticus Contamination in the Pacific Oysters (Crassostrea gigas)

    Creator:
    Shen, Xiaoye
    Abstract:
    Vibrio parahaemolyticus is the leading cause of foodborne illnesses associated with seafood consumption. Consuming raw or undercooked seafood contaminated with V. parahaemolyticus can result in development of acute gastroenteritis with symptoms of nausea, vomiting, abdominal cramping and watery diarrhea within 24 hours of infection. Illness is usually self-limited and lasts...

  • Commercial application of high pressure processing for inactivating Vibrio parahaemolyticus in Pacific oysters (Crassostrea gigas)

    Creator:
    Ma, Lei
    Abstract:
    Vibrio parahaemolyticus is a Gram-negative, halophilic pathogen that occurs naturally in coastal and estuarine environments. This human pathogen is frequently isolated from a variety of seafood, particular oysters, and is the leading cause of gastroenteritis associated with seafood consumption. Several outbreaks of V. parahaemolyticus infections linked to consumption of raw...

    Creator:
    Wu, Xulei
    Abstract:
    Staphylococcus aureus is a human pathogen capable of producing enterotoxins causing staphylococcal food poisoning, one of the most economically important foodborne diseases in the U.S. This pathogen may be introduced to pre-cooked tuna meat used for the production of canned tuna because significant manual handling occurs after cooking of the...
