  • Novel Approaches to Evaluate the Environmental Impacts of Nanomaterials

    Creator:
    Wu, Fan
    Abstract:
    Numerous studies have shown that some nanomaterials are highly toxic to aquatic organisms and can potentially disrupt overall community health; however, current methods to evaluate the nanomaterials environmental impacts rarely consider the environmental realism or provide sufficient detail on the impact at the community level. Here we demonstrate three approaches...

  • 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...

  • Addressing the Risks of Nanoscale Polymers: Exposure, Behavior, and Toxicity

    Creator:
    Stine, Jared
    Abstract:
    Nanoscale polymers (including nanoplastics) are widely present through commerce and make their way into the environment. As the improper disposal of plastic waste leads to continued accumulation and degradation of plastic pollution, the presence of plastic particles less than 1 micron (μm) in size (nanoplastics) will increase. Heightened concern over...

  • 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...

  • 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...
