  7. Grand Challenge Workshop Nanotechnology and the Environment May 8-9, 2003

  8. Environmental Applications for measurement in the environment: Vision:The unique properties of nanoscale materials will enable the development of a new generation of environmental sensing systems. Measurement science and technology will enable the development of a comprehensive understanding of the interaction and fate of natural and anthropogenic nanoscale and nanostructured materials in the environment.

  9. Research needs: 1. Biological sensor technologies that are sufficiently stable to allow detection in situ on a continuous basis for high-density usage 2. A general “array” for detection of a wide variety of potential analytes

  10. 3. Information concerning the diversity of chemical composition at the nanoparticle level, and the transformations that occur and measurement techniques that distinguish the chemical composition of particle surface layers from the particle interior 4. Generic nanoscale assembly methods 5. Advances in spectroscopic instrument technologies that allow rapid detection of low signal strength, while probing the smaller volumes of a nano-particulate sample

  11. Our goal: Co-optimize the environment as part of nanotechnology development This can be accomplished only with the underlying work from instrumentation and metrology
