Chronic Toxicological Effects in Daphnia magna from Exposure to PMMA Nanoplastics

Creator:: Brown, Hans
Abstract:: Plastic pollution is an ever-increasing environmental threat. As large-scale plastics break down to form nanoscale plastics, it is essential to investigate their effects on freshwater ecosystems. With many plastic nanoparticle (NP) studies favoring the effects of common polystyrene (PS) plastics, a gap is formed for other common plastic types like...

Environmental Transformations in Hydrophobicity of TiO2 P-25 Nanoparticles in Alsea River Waters

Creator:: Boenisch, Kylie
Abstract:: Hydrophobic titanium dioxide (TiO2) nanoparticles (NPs) are prevalent in industry and manufacturing. They are known for their white pigmentation, are found in sunscreens, paints, cosmetics, and are frequently used in wastewater treatment. Understanding the physicochemical properties of TiO2 P-25 NPs, such as hydrophobicity, are essential when determining their fate, transport,...

Optimizing Methods to Assess Nanoparticle Biodistribution in Embryonic Zebrafish

Creator:: Pfarr, Shaylin H.
Abstract:: As nanoparticle (NP) research and development expands, the significance of NP biodistribution effects on toxicity increases. A reliable method for measuring NP biodistribution is critical. Hyperspectral Imaging (HSI) is capable of accurately quantitating NP biodistribution within embryonic zebrafish with incredibly high precision. Before HSI processing, the embryo must be sectioned...

Developmental effects of micro- and nanoscale tire particles and recycled rubber on zebrafish

Creator:: Mottern, Taylor H.
Abstract:: Plastics have become an essential part of everyone lives, found in almost every product made today. Tires only make up a fraction of these products but as their use increasing so does the microplastics that flake off. Many studies have evaluated the toxic effects of tire particles on aquatic environments...

Comparative toxicological assessment of PAMAM and thiophosphoryl dendrimers using embryonic zebrafish.

Creator:: Pryor, Joseph Brian
Abstract:: Dendrimers are well-defined, polymeric nanomaterials currently being investigated for their biomedical applications. Initially, higher generation (size) dendrimers were of interest because of their drug carrying capacity. However, increased generation was associated with increased toxicity. The objective of the present study was to investigate the role of surface charge and generation...

Reduced toxicity of benzethonium chloride to Escherichia coli through adsorption onto titanium dioxide nanoparticles

Creator:: Waldron, Kerri Raven
Abstract:: Antimicrobial agents are being increasingly used in consumer soaps and detergents, despite a lack of data demonstrating their efficacy in such products. This study investigated the nature of the interaction between different crystalline structures of titanium dioxide nanoparticles and BTC, and explore which structure, if any, could be best used...

Environmental Transformations of Nanoparticles in Natural Water Systems using a Hydrophobic and Hydrophilic Dye Assay

Creator:: Turnquist, Macklin C.
Abstract:: Nanoparticles (NPs) are generally defined as particles <100 nanometers (nm) in size in one dimension. Despite increasing industrial usage of TiO2 NPs in sunscreens, cosmetics, and water remediation little is known of their environmental behavior. The primary goal of this research was to develop a rapid method for determining the...

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...

The Stability, Toxicity, and Reactivity of Zero Valent Iron Nanoparticles

Creator:: Bulovsky, Hannah G.
Abstract:: Zero valent iron nanoparticles effectively remediate groundwater contaminants due to their catalytic properties and enhanced surface area. However, these properties contribute to particle agglomeration, decreasing their effectiveness. In this study, we examined the effect of two stabilizing agents (gum arabic (GA) and sodium carboxymethyl cellulose (CMC)) on particle stability, toxicity,...

Beyond the Carpetbagger: The Emergence of Racialized Terms as a Political Weapon in the Reconstruction Era South

Creator:: Farrington, Caprial E.
Abstract:: The Reconstruction era, beginning in 1863, was a time of radical change and movement in American politics and society. A significant number of northern Republicans migrated southwards, for various purposes, including political involvement. To white Democratic southerners who believed they had just fought a war of northern aggression and now...
