Abstract
The explosion of research into carbon-based nanomaterials has been driven by their possible application to a wide range of fields. While materials such as graphene and cellulose nanostructures show great potential due to their physical qualities, understanding of their stability and toxicity is still not well-defined. This report explores the result of exposing new and familiar nano-sized carbon architectures to oxidative environments, with the intent of furthering the safe and effective implementation of them. First, intentional degradation of graphene oxide is exhibited through the use of iron oxide nanoparticles as a component in the Fenton reaction. Next, the morphologies of different nanocellulose sources are thoroughly characterized using microscopy techniques. The interaction between myeloperoxidase and one of these nanocellulose samples, which results in acute aggregation, is then investigated. An additional degradation system utilizing DNA origami and horseradish peroxidase is also introduced as a possible approach for graphene oxide degradation. Finally, two emerging nanomaterials, carbon nanofibers and chitin, are analyzed and their pulmonary toxicity assessed in collaboration with the National Institute of Occupational Safety and Health.
