An in silico Approach to Determine the Influence of Surface Chemical Properties on the Toxicity of Engineered Zinc Oxide Nanoparticles

Creator:

Zhou, Zitao

Abstract:

Nanotechnology products have long since made their way to markets around the world increasing the concerns about whether nanomaterials pose a risk to our environment or health. It has been suggested that engineered nanomaterial (ENM) with broad applications and rapid commercialization need better risk assessment and regulation. However, the refinement...

Heteroaggregation of gold nanoparticles with model colloids and the influence of environmental aqueous chemistry

Creator:

Pike, Daniel J.

Abstract:

Nanoparticles are becoming increasingly important in numerous technological fields but evidence shows that they can be toxic to many organisms. To predict their fate and transport in the environment, nanoparticle attachment to naturally occurring colloids must be examined. This study investigated citrate-capped gold nanoparticle (Cit-AuNP) heteroaggregation with two model colloids...

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....

Transformation of Phenanthrene by Mycobacterium sp. ELW1 and the Formation of Toxic Metabolites

Creator:

Schrlau, Jill E.

Abstract:

The ability of Mycobacterium sp. ELW1, a novel microbe capable of alkene oxidation, to co-metabolize phenanthrene (PHE) was studied. ELW1 was able to completely co-metabolize PHE, at different concentrations below its water solubility limit, in an aqueous environment. The alkene monooxygenases in ELW1, used to initiate oxidation of PHE, were...

Inhibition of the ammonia oxidizing bacteria Nitrosomonas europaea by the emerging contaminant triclosan

Creator:

Hughes, Jamie L.

Abstract:

Identifying the inhibition of ammonia oxidizing bacteria (AOB) by emerging organic contaminants is crucial due to the importance of AOB in wastewater treatment, the widespread use of antibacterial agents such as triclosan (TCS) in consumer products, and the sensitivity of N. europaea to inhibitors. Triclosan inhibition of nitrification by AOB...

Development of traceable metal oxide nanoparticles for examining environmental fate and transport

Creator:

Rowbotham, Brian

Abstract:

The fate and transport of engineered nanoparticles (ENPs) such as titanium dioxide (TiO₂) are of concern due to their increasing use in consumer products. Although analytical methods for detection and quantification of ENPs in environmental matrices are being developed, these methods are difficult, time consuming, and not easily validated for...

Method development for characterizing the hydrophobicity of engineered nanoparticles

Creator:

Lee, Fang Yu

Abstract:

Characterizing the hydrophobicity of nanoparticles can help us understand their fate and transport in the environment, as well as how nanoparticles may interact with biological systems. However, contact angle and partition coefficient have limitations in measuring the hydrophobicity of nanoparticles, thus promising methods to measuring the hydrophobicity of nanoparticles are...

Studies on effect of stabilizers, chelators and inherent periodicity on nanoparticle antioxidant activity

Creator:

Zhou, Zheng

Abstract:

The level of reactive oxygen species (ROS) is tightly regulated in biological systems as overproduction can lead to oxidative stress and result in a number of diseases. Due to its negative effects, antioxidants are studied and used against ROS in medicine, pharmaceuticals and therapeutics. Because of issues with the uptake...

Physiological response of Nitrosomonas europaea to oxytetracycline, chromium, and silver

Creator:

Schaerer, Morgan A.

Abstract:

Nitrosomonas europaea carries out the first step in the biological nitrogen removal process in wastewater treatment by oxidizing ammonia to nitrite. It has been shown to be sensitive to a wide range of contaminants. The antibiotic oxytetracycline and the heavy metals chromium and silver have been found in wastewater influent....

Development and applications of a high-throughput activity assay, using the ammonia-oxidizing bacteria Nitrosomonas europaea

Creator:

Bartow, Shannon M.

Abstract:

The rising demand on freshwater resources emphasizes the benefit of biogeochemical processes that maintain clean water by removing pollutants such as excess nitrogen. The most sensitive step in the removal of nitrogen from waterways is the oxidation of ammonia, a part of nitrification, which is carried out by ammonia oxidizing...
