Nanotechnology involves imaging, measuring, modeling and manipulating matter at the nanoscale of approximately 1 to 100 nanometers. It allows scientists to see and manufacture materials at the atomic scale using techniques like scanning tunneling microscopes. Nanotechnology has applications in electronics such as transistors and displays, energy with batteries and solar cells, materials like carbon nanotubes, and life sciences for targeted drug delivery and tissue regeneration. Advocates argue it will lead to stronger, lighter and cheaper materials while critics warn of potential environmental and health risks from nanomaterials. The future of nanotechnology is predicted to include electronic paper, morphing devices and smart contact lenses that will transform many everyday objects over the next century.

8. Seeing at nanoscale
Nanoscientists use high-powered microscopes that
use unique methods to allow them to see the surface
features on the atomic scale, effectively opening the
door to modern nanotechnology such as scanning
tunneling microscope and the atomic force
microscope.

9. Manufacturing at the nanoscale
Nanomanufacturing involves scaled-up, reliable, and
cost-effective manufacturing of nanoscale materials,
structures, devices, and systems.
It leads to the production of improved materials and
new products.

10. How it works?
Encompassing nanoscale science, engineering, and
technology, nanotechnology involves imaging,
measuring, modeling, and manipulating matter at
this length scale.
