The National Nanotechnology Infrastructure Network ( NNIN ) is an integrated partnership of thirteen user facilities, supported by NSF, providing unparalleled opportunities for nanoscience and nanotechnology research. NNIN is funded by a cooperative agreement with the National Science Foundation as a national resource for nanoscience instrumentation.

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.
