What is nanotechnology?
Nanotechnology is science, engineering and technology conducted at the nanoscale, about 1 to 100 nanometers. How small is that? Pretty small: a single sheet of paper is about 100,000 nanometers thick!
At the nano level, scientists and engineers look to control individual atoms and molecules to do some pretty amazing things. Right now, researchers are using nanotechnology to push boundaries and solve major challenges in energy, health, materials science and more. Use these resources on this page to learn more about nanotechnology and what it means for our future.

World's Smallest Periodic Table
At only 14 by 7 μm, this teeny tiny table was etched on a silicon chip using scanning electron microscopy in honor of the International Year of the Periodic Table (IYPT).
Nanoparticles, in green, were incubated with red blood cells from mice. When reinjected through an arterial catheter, the carrier blood cells accumulate in the nearest organ which could have applications in drug delivery.
This image was the winner of C&EN’s National Nano Day Photo Contest in 2017. Scientists at Wilfrid Laurier University made these flower-shaped silver nanoparticles. Each flower is roughly 300 nm in diameter.
This blue ice crystal is embedded in an aluminum alloy surface that has been laser textured and chemically coated to help create a surface that is resistant to ice coating, making it useful for aviation.
Semiconductor nanoparticle called quantum dots make up this festive tree. By changing the size of the particles which are chemically identical, researchers can modify electronic properties including their color.
Forming Good Habits
Scientists at Merck & Co. in Rahway, N.J., are researching these crystals, which were made by crystallizing the same small-molecule drug candidate yet have noticeably different shapes, or crystal habits.
(Really) Tiny House
Jean-Yves Rauch and colleagues at FEMTO-ST Institute constructed this 15-μm-tall house out of thin silica membranes. The team used a dual-beam scanning electron microscope and focused ion beam to erect the teeny domicile.
