Environmental Implications of Nanomaterials: Biological Interactions

Tuesday, October 18, 2011: 12:30 PM
212 A (Minneapolis Convention Center)

Description:
Engineered nano-scale materials have the potential to transform medical diagnostics, high-performance materials, and to dramatically increase the performance and energy efficiency of sensors, consumer electronics, and energy conversion and storage devices. However, before the full potential of nanotechnology can be realized, potential adverse interactions between novel materials and the natural environment must be better understood. The specific goal of this session is to highlight the latest research on interactions between nanomaterials and microbes, lipid membranes, or other forms of biota.
