Nanotechnology is the understanding, manipulation, and control of matter at the nanoscale, typically between 1 and 100 nanometers. At this scale, materials exhibit unique physical, chemical, and biological properties, leading to novel applications across various fields. Nanotechnology involves both the “top-down” approach of breaking down bulk materials into nanoscale components and the “bottom-up” approach of building structures from atoms and molecules.

The vision of the National Nanotechnology Initiative (NNI) is a future in which the ability to understand and control matter at the nanoscale leads to ongoing revolutions in technology and industry that benefit society.

The National Nanotechnology Initiative (NNI) is a U.S. Government research and development (R&D) initiative. Over thirty Federal departments, independent agencies, and commissions work together toward the shared vision of a future in which the ability to understand and control matter at the nanoscale leads to ongoing revolutions in technology and industry that benefit society. The NNI enhances interagency coordination of nanotechnology R&D, supports a shared infrastructure, enables leveraging of resources while avoiding duplication, and establishes shared goals, priorities, and strategies that complement agency-specific missions and activities.
