Nano Day 2025: nanoStories—a brief look into the ways the world is put together

October 9 is National Nanotechnology Day—the day that celebrates the potency of the world at the scale of one nanometer, 10-9 or one billionth of a meter. Every year, we celebrate 10/9 to shine a light on the potential of nanoscale discoveries and innovations to help solve some of the biggest challenges facing society today.

This year, MIT.nano is unveiling the first in a collection of nanoStories — brief snippets that tell how our everyday experiences are shaped by what happens at the nanoscale. This collection is designed for human explorers aged 11-100, who are curious about the way the world is put together.


 

Everyone can tell a nanoStory. This collection was crafted by the imagination and excitement of students who took part in MIT.nano's nanostories workshop during MIT's Independent Activities Period (IAP) 2021 to 2023. Many more stories could be told. We invite you to suggest topics that could be part of the next collection.

Have an everyday question you'd like answered at the nanoscale? Submit it here to be included in a future nanoStory!
