The National Nanotechnology Infrastructure Network ( NNIN ) is an integrated partnership of fourteen user facilities, supported by NSF, providing unparalleled opportunities for nanoscience and nanotechnology research.

The network  provides extensive support in nanoscale fabrication, synthesis, characterization, modeling, design, computation and hands-on training. in an open, hands-on environment, available to all qualified users.

The members of NNIN include the following major nanotechnology user facilities:

• The Cornell Nanoscale Facility at Cornell University
• The Stanford Nanofabrication Facility at Stanford University
• The Lurie Nanofabrication Facility at the University of Michigan
• The Nanotechnology Research Center at the Georgia Institute of Technology
• The Center for Nanotechnology at the University of Washington 
• The Penn State Nanofabrication Facility at the Pennsylvania State University
• Nanotech at the University of California at Santa Barbara
• The Nanofabrication Center  at the University of Minnesota
• The Microelectronics Research Center at University of Texas at Austin
• The Center for Nanoscale Systems at Harvard University
• The Howard Nanoscale Science and Engineering Facility at Howard University
• The Nano Research Facility at Washington University at St. Louis
