 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 advance a world-class nanotechnology research and development R&D program, foster the transfer of new technologies into products for commercial and public benefit, develop and sustain educational resources, the skilled workforce, and the supporting infrastructure and tools to advance nanotechnology, and support responsible development of nanotechnology.
