While several manufactured engineered nanomaterials (ENMs) are currently in the market, there are concerns that the uniformity in particle size, shape, and morphology of a given sample is often poor. This makes understanding the reactivity and behavior of ENMs in the environment difficult since the reactivity of ENMs is highly dependent on size, shape and morphology. Our group has thus focused on developing straightforward synthetic procedures for the production of well-defined metallic, bimetallic and metal oxide nanoparticles in high yield. Electrochemical, x-ray, and surface probe microscopy are a few of the fundamental techniques used to characterize our ENMs. The presentation will focus on understanding the mechanisms by which ENMs interact with microbial pathogens common in the environment, and to obtain a fundamental understanding of how these interactions are influenced by environmental factors. We will also discuss the effect of interactions of microbial pathogens with biomolecules at the interface of well-defined ENMs.
