About this collection
National Nanotechnology Day is an annual celebration in the US featuring a series of 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. More information is available here: https://www.nano.gov/node/2553
Now in its fourth year, the theme for this year's National nanotechnology Day is: "Building the Future with Nano."
To celebrate we have put together a series of top articles by US researchers published recently across the nanoscale journal family. We hope that you enjoy reading them!
Articles free to access until the end of October 2019.
