National Nanotechnology Day

Event Date

National Nanotechnology Day is an annual event featuring community-led events and activities on or around October 9 to help raise awareness of nanotechnology, how it is currently used in products that enrich our daily lives, and the challenges and opportunities it holds for the future. This date, 10/9, pays homage to the nanometer scale, 10–9 meters.

This year, National Nanotechnology Day is going virtual! Whether at home or outside, let’s explore ways to highlight advances in nanotechnology and how it is impacting our everyday lives.

Here are a few ideas you could try:

  • Create an image, video, illustration, or infographic about nanotechnology: what it is, why it is important, and examples of nanotechnology applications.
  • Host image, video, or illustration contests related to nanotechnology.
  • Host a virtual informal discussion on nanotechnology with a scientist from local college or university.
  • Sizing up Nano: How do you explain what a nanometer is? Or what a nanoparticle or a nanodevice look like? We welcome your thoughts! Send us your explanations, pictures, and videos to, or send a Tweet by using #NationalNanoDay!




 In addition, the National Nanotechnology Coordination Office is promoting:

  100-Billion Nanometer Dash: Run #100BillionNanometers, ask someone to take a video or picture, and        then post it on social media with #NationalNanoDay!
