  • Applications of Holographic Optical Tweezers: Multiplexed Fluorescence Spectroscopy and the Micromechanics of Type-I Collagen

    Creator:
    Cibula, Matthew A.
    Abstract:
    The development and some applications of holographic optical tweezers (HOT) are presented. Our HOT system uses a spatial light modulator (SLM) to control the location and properties of the optical trap. We have developed a method for optimizing the diffraction efficiency of a SLM that can be applied in situ...

  • High-Field Terahertz Spectroscopy of Nanoscale Materials

    Creator:
    Mousavian, Ali
    Abstract:
    This dissertation covers my work relating to the application of strong terahertz (THz) radiation to study the nonlinear properties of nano-scale material. It presents experimental and numerical studies on the optical and electronic properties of various material system including single-layer graphene, multi-walled carbon nanotubes (MWCNTs), nanoantenna-patterned gallium arsenide (GaAs) and...

  • Bioelectronic Systems for Neurosensing Enabled by Graphene

    Creator:
    Fengel, Carly V.
    Abstract:
    Taking long-term electrical measurements of a large number of neurons simultaneously is required for many modern neuroscience experiments. However, such experiments are currently limited by the shortcomings of traditional neurosensing technology. For example, there is a significant mechanical mismatch between rigid silicon probes and soft biological tissues. This mismatch can...

  • Gene Expression, Structure Elucidation, and Bioactivity of Aspergillus Natural Products

    Creator:
    Neuhaus, George F.
    Abstract:
    The study of natural products (NPs) and their application has shaped humanity. Starting with the idea of using plants as medicine, it has now grown into the science of purifying and identifying organic molecules from nature to study their inherent biological activities. Understanding the molecular structures of NPs is the...

  • Functional Materials and Techniques for Additive Manufacturing in Soft Robotics

    Creator:
    Walker, Stephanie
    Abstract:
    This thesis outlines the development of new elastomeric materials and manufacturing processes for soft robotics. Specifically, this work describes the development of custom material formulations for use in additive manufacturing, additive manufacturing processing techniques for silicone elastomers, and multi-component additive manufacturing techniques. Material synthesis and processing is a gap in...

  • Conformational Consequences: Calcium Regulates the Association Between Dysferlin C2A & PI(4,5)P2

    Creator:
    Otto, Shauna C.
    Abstract:
    Dysferlin is a ∼230 kDa terminally anchored membrane protein that is ubiquitously expressed, but is particularly enriched in skeletal and cardiac muscle tissue. Mutations covering the length of the protein have been linked to muscle wasting diseases including limb-girdle muscular dystrophy and Myoshi myopathy. Dysferlin has been shown to play...

  • Total synthesis of sparteine alkaloids from a common tetraoxobispidine intermediate

    Creator:
    Melbardis, John
    Abstract:
    In previous work (Blakemore et al. Org. Lett. 2005, 7, 4721; Heterocycles 2006, 70, 609), successful elaborations of the lupine alkaloids (±)-α-isosparteine (dl-2) and (±)-β-isosparteine (dl-3) were realized from a common tetraoxobispidine precursor, 3,7-diallyl -2,4,6,8-tetraoxo-3,7-diazabicyclo[3.3.1]nonane (93). Herein, the tetraoxobispidine approach to lupine alkaloids was extended to a total synthesis of...

  • Scanning photocurrent microscopy study of photovoltaic and thermoelectric effects in individual single-walled carbon nanotubes

    Creator:
    DeBorde, Tristan
    Abstract:
    Carbon Nanotubes are a unique family of nanostructures that have shown remarkable promise for mechanical, electrical, and optical applications. Fundamentally similar to the earlier discovered Buckminsterfullerene (C₆₀), carbon nanotubes are hollow cylinders formed from a single sheet of carbon atoms. The research presented in this dissertation investigates several carbon nanotube...

  • Terahertz imaging and spectroscopy of carbon-based and semiconductor nanostructures

    Creator:
    Tomaino, Joseph L.
    Abstract:
    This thesis will cover work that I have completed relating to the field of terahertz (THz) science. My work has consisted of generating tunable, narrowband THz pulses in a table-top optical setup and using both narrow- and broadband THz pulses to study various material systems. Broadband THz pulses were used...

  • Computational nanooptics in hyperbolic metamaterials and plasmonic structures

    Creator:
    Thongrattanasiri, Sukosin
    Abstract:
    This dissertation concerns several problems in the fields of light interaction with nanostructured media, metamaterials, and plasmonics. We present a technique capable of extending operational bandwidth of hyperbolic metamaterials based on interleaved highly-doped InGaAs and undoped AlInAs multilayer stacks. The experimental results confirm theoretical predictions, exhibiting broadband negative refraction response...
