cnt-handling-smallThis week’s issue of C&E News has a great article on the MINChar initiative by Britt Erickson.

Just as a taster, two quotes from the article:

Clayton Teague, director of the National nanotechnology Coordination Office:

“There is a great need for improved characterization of the nanomaterials used in toxicity studies. Everyone recognizes that the materials used in many of the earlier studies were not adequately characterized, and some of the conclusions should not have been drawn,” says E. Clayton Teague, director of the National Nanotechnology Coordination Office, which coordinates federal nanotechnology R&D activities.

Kristen Kulinowski, director of ICON:

Kristen M. Kulinowski, director of the International Council on Nanotechnology at Rice University, agrees. “All of these allied efforts, each doing something a little bit different, will someday advance the quality of nanotechnology-risk-relevant research and help decision-making at the policy level,” she says.

At the October 28-29 workshop, a number of criteria and recommendations formed the basis of discussions on a minimum set of characterization parameters for nanotoxicology studies.

This presentation (PDF, 284 KB) put together by Nigel Walker (National Institute of Environmental Health Sciences), Richard Pleus (Intertox Inc) and Richard Canady (FDA) provided a starting point for discussions.
