Description:: Like many diseases, atherosclerotic cardiovascular disease is driven by the activity of inflammatory cells. Using molecular imaging to target and analyze populations of inflammatory cells is one promising strategy to non-invasively assess atherosclerosis progression. However, current molecular imaging contrast agents are not suited for such targeted imaging applications. Nanomaterial-based strategies...

Description:: Due to their widespread use and subsequent release, ENMs may exist as mixtures in the natural environment where their chemical interactions can control the toxic stress to exposed microorganisms. Will complex environmental mixtures containing ENMs produce microbial stress that is synergistic, attenuated, or simply additive relative to single ENM exposure,...

Description:: This dissertation describes modifications to the surface of colloidal semiconductor quantum dots (QDs) to improve their use as photocatalysts for charge transfer reactions. The surface atoms and ligands of these nanoparticles can interfere with direct charge transfer to a reagent by inhibiting binding, forming trap states, or acting as competitive...

Description:: This dissertation investigates the use of organic and semiconductor nanomaterials as chromophores in solar fuels production and energy transfer-mediated [2+2] cycloadditions. A series of novel N-annulated perylene chromophore amphiphiles was synthesized via a modular synthesis. These perylene amphiphiles were found to self-assemble in aqueous solution, forming extended ribbon-like nanostructures that...

Description:: The expanding use of nanomaterials in consumer products challenges scientists to understand the impact of these materials before their inevitable release into the environment. In the same way that the widespread use of DDT and asbestos has caused unforeseen negative impacts on both the environment and on human health, the...

Description:: The rational and deliberate assembly of functional materials from nanoscale building blocks requires a fundamental understanding of interactions between individual components as well as their collective behavior. This thesis investigates the hierarchical organization of nanoparticles using DNA into well-defined three-dimensional materials on the micrometer and millimeter length scales. This assembly...
