National Nanotechnology Day

Event Date
Celebrate how the world’s smallest technologies shape our daily lives
October 9, 2025

The annual National Nanotechnology Day takes place on October 9, a date chosen to honor the nanometer scale (10-9 meters). This nationwide celebration highlights how nanotechnology enriches our daily lives today and the exciting opportunities it offers for the future. Schools, universities, and organizations across the country will join in to showcase and explore the impact of this transformative science.

How to Celebrate National Nanotechnology Day

At Home
  • Host a scavenger hunt centered around household items that are nanotechnology-enabled.
  • Create and share an image, video, illustration, or infographic about nanotechnology, including what it is, why it is important, and examples of applications.
  • Size up Nano: Help explain what a nanometer is by sending explanations, pictures, and videos to nnd@nnco.nano.gov or by tagging posts with #NationalNanoDay.
