In collaboration with several colleagues, we are investigating multiple aspects of the fate, transport, and toxicity of nanomaterials. In a joint effort with Prof. Jean-Claude Bonzongo from Environmental Engineering Sciences, we have been coupling processing data with toxicity measurements to improve the processing of SWNTs while simultaneously reducing their eco-toxicity. In related work, in collaboration with Prof. Bin Gao from Agricultural Engineering we have measured the transport of SWNTs through different types of soils. Finally, we have been working with Prof. Tanmay Lele Chemical Engineering to investigate the growth of biological cells on nanowire arrays with the goal of improving the performance and human-compatibility of biomedical devices.
