In a vote of confidence that nanotechnology might be the next big thing, Congress has passed the 21st Century Nanotechnology Research and Development Act. The law authorizes $3.7 billion in spending on nanotechnology over 4 years starting Oct. 1, 2004. It also calls for the creation of a national research hub–the American Nanotechnology Preparedness Center–charged with investigating the societal, ethical, and environmental implications of this rapidly growing field.
Nanotechnology is the study and manipulation of materials on atomic and molecular scales measured in billionths of a meter. Scientists propose that such research could lead to more-precise medical therapies, ultrafast computing devices, and new materials that can clean up the environment. However, the effects of nanomaterials on the body and the environment remain unclear.
