Assessing Changes in Biological Interactions of Lipid-Coated Gold and Silver Nanoparticles Based on Physicochemical Properties

Creator:: Engstrom, Arek Mackenzie
Abstract:: Nanoparticles (NPs), particles defined by their size in a single dimension (1-100 nm), are being increasingly incorporated into commercial and industrial products due to their high surface area to volume ratio that gives them unique properties, such as optical tunability and higher reactivity than their bulk counterparts. NPs can be...

Analyzing the use of the acellular DCFH assay as a means of determining oxidative stress induced in zebrafish embryos exposed to lanthanide oxide nanoparticles

Creator:: Engstrom, Arek
Abstract:: The ability of nanoparticles (NPs) to induce oxidative stress on organisms has been linked to NP cytotoxicity and genotoxicity for a variety of organisms. One proposed mechanism of this increased oxidative stress is the ability of NPs to generate reactive oxygen species (ROS). Due to the dynamic nature and small...

Spherical Au Nanoparticle Interaction with Lipid Monolayers Probed with Sum Frequency Generation Spectroscopy

Creator:: Faase, Ryan A.
Abstract:: Nanoparticles have become more prevalent from their use in sunscreen to antimicrobial agents in socks. In light of these applications, gaining a fundamental understanding of how NPs interact with humans is crucial for their future. Specifically, how cells interact with NPs and what factors drive the modes of cellular uptake....

Design of a 3-D Printed Eye Model for Quantification and Analysis of Retinal Image Distortion in the Ophthalmic Plaque Brachytherapy Treatment Planning Process

Creator:: Smith, Lauren D.
Abstract:: Ophthalmic plaque brachytherapy is a form of internal radiation treatment for uveal melanoma, the most common eye cancer in adults. During treatment, a plaque containing radioactive seeds is surgically attached to the sclera, directly adjacent to the ocular tumor site. Plaque Simulator™ is an eye plaque brachytherapy planning software that...

Death by dissolution : sediment saturation state as a mortality factor for juvenile bivalves

Creator:: Green, Mark A., Waldbusser, George G., Reilly, Shannon L., and Emerson, Karla
Abstract:: We show that death by dissolution is an important size-dependent mortality Utilizing a new experimental design, we were able to replicate saturation states frequently encountered by Mercenaria mercenaria in coastal deposits mercenaria were reared in sediments at Ωaragonite = 0.4 and 0.6, significant occurred (14.0% and 14.4% d⁻¹, respectively), relative...

Addressing Persistent Challenges in Nanotoxicology Exposures : Techniques for in situ Characterization

Creator:: Crandon, Lauren E.
Abstract:: Nanoparticles (NPs), defined by their size (1-100 nm), are increasingly incorporated into commercial and industrial products due to their high surface area and unique properties. They can be designed for specific applications by manipulating composition, size, shape, and surface functionalization. As NP production and complexity increases, there is a need...

Influence of River Plumes on Larval Fish Distributions, Predator-Prey Relationships, and Fitness in the Northern Gulf of Mexico

Creator:: Axler, Kelia E.
Abstract:: River plumes discharging into continental shelf waters have the potential to influence patchiness of larval fishes, prey, and gelatinous predators. Using a high-resolution plankton imaging system, we sampled larval fishes, copepods, and planktonic predators (ctenophores, hydromedusae, and siphonophores) across multiple freshwater pulses exiting the mouth of Mobile Bay (Alabama, USA)...
