Nanotechnology

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.


Webinars

Combating Climate Change with New Nanobugs: Teaching Bacteria to Eat Carbon Dioxide and Light with Quantum Dots
Prashant Nagpal of the University of Colorado Boulder discusses the development of living nano-biohybrid organisms that use sunlight to convert massive amounts of carbon dioxide, air, and water into biodegradable plastics, fuels and more. 

Advances in Graphene Nanotechnology: Making the Paralyzed Walk
James Tour and William Sikkema of Rice University describe how rats that have had their spinal cords completely severed in two were restored to near perfect mobility.

Nano 2.0: Multi-scale Nanomaterials
Discover how assembling nano super-structures opens possibilities for new classes of multi-scale nanomaterials with unprecedented physical characteristics.

Working Safely with Nanomaterials in the Laboratory
Join Ken Kretchman of N.C. State University, Craig Merlic of UCLA, Debbie Decker of UC Davis as well as moderator Chuck Geraci of NIOSH, as they discuss the importance of managing products containing nanomaterials by integrating them into an existing lab safety program.

Nanomaterial Design Guided by the Principles of Green Chemistry
James Hutchison discusses the foundations for greener nanotechnology and presents a case study that uses nanomaterial product innovation guided by green chemistry.

National Nanotechnology Day

October 9 is National Nanotechnology Day in honor of the nanometer scale, 10-9 meters. The goal of Nano Day is to 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.

Learn more and see how ACS celebrated Nano Day 2017.

Federal Support

Federal support is vital to nanotechnology research. The National Nanotechnology Coordination Office (NNCO) is responsible for coordinating a $23 billion initiative that spans 20 Federal agencies. Learn more about the NNCO.

Image Gallery

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).

Nanoparticle Carrier
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.

Acoustic Protein Nanostructures
Gas vesicles are gas-filled nanostructures.  They scatter sound waves and have customizable shells, making them potential ultrasound contrast agents.

Silver Nanoflowers
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.

"Icephobic" Aluminum
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.

Tiny Turtle
This happy, 9-μm-wide turtle is made from a titanium carbide (Ti3C2) MXene particle.

Quantum Chemistree
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.

Nano Bible
Measuring in at 20 nm thick and 0.04 mm² in area, the world’s smallest Bible can only be read with a microscope.

(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.

Nanoroses in Bloom
These exquisite nanoroses were created from common borax exposed to high temperatures and oleic acid. Under different reaction conditions, different structures can be formed.
