 There is also a nanomanufacturing program at the U.S. National Science Foundation, through which the National Nanomanufacturing Network (NNN) has been established.The NNN is an organization that works to expedite the transition of nanotechnologies from laboratory research to production manufacturing and it does so through information exchange, strategic workshops, and roadmap development.The NNI has defined nanotechnology very broadly, to include a wide range of tiny structures, including those created by large and imprecise tools.
