NNI's 2014 enacted budget by agency.
The National Nanotechnology Initiative is a United States federal government program for the science, engineering, and technology research and development for nanoscale projects. “The NNI serves as the central point of communication, cooperation, and collaboration for all Federal agencies engaged in nanotechnology research, bringing together the expertise needed to advance this broad and complex field.” Initiative participants (cited below) state that its four goals are to
Mihail Roco proposed the initiative in a 1999 presentation to the White House in the Clinton administration.
President Bill Clinton advocated nanotechnology development. In a 21 January 2000 speech [1] at the California Institute of Technology, Clinton stated that "Some of our research goals may take twenty or more years to achieve, but that is precisely why there is an important role for the federal government."
President George W. Bush further increased funding for nanotechnology. On December 3, 2003 Bush signed into law the 21st Century Nanotechnology Research and Development Act (Public Law 108-153 [2]), which authorizes expenditures for five of the participating agencies totaling $3.63 billion over four years.[3]. This law is an authorization, not an appropriation, and subsequent appropriations for these five agencies have not met the goals set out in the 2003 Act. However, there are many agencies involved in the Initiative that are not covered by the Act, and requested budgets under the Initiative for all participating agencies in Fiscal Years 2006 - 2015 totaled over $1 billion each.
