A U.S. scientific panel is calling for a systematic study of the growing use of nanomaterials in industry, saying little is known about the risk of the microscopic particles increasingly being used in everythingNanotech: The Unknown Risks
Nanotechnology, now used in everything from computers to toothpaste, is booming. But as Carole Bass reported in 2008, there were already rising concerns that its development was outpacing our understanding of how to use it safely.

The National Research Council (NRC), part of the U.S. National Academy of Sciences, noted that the use of nanomaterials — measured on the scale of billionths of a meter — is growing rapidly, rising from $225 billion in nanotechnology-based products in 2009 to an estimated $3 trillion by 2015.
