United States National Nanotechnology Initiative

The United States National Nanotechnology Initiative (NNI) is a government program that promotes research and development of nanotechnology—science and engineering at extremely small scales, millions of times thinner than a human hair. Its goal is to advance innovations in medicine, electronics, energy, and materials by supporting collaboration among agencies, funding research, and fostering responsible development. The NNI aims to improve everyday life through technological breakthroughs while ensuring safety and ethical considerations are addressed in the progress of nano-scale science.
