LESSON 4: THE NANO WORLD
Just as human understanding of the natural world was revolutionized by the discovery of light
microscopes, modern microscopes that can expose and change individual atoms are once
again exposing a whole new world-the nano world. Scientific researchers have developed new
technological tools that greatly improved different aspects of our lives through the use of
nanoscale.
What is nanotechnology?
Nanotechnology refers to the science, engineering, and technology conducted at the
nanoscale. It is concerned with building 'things' -generally, materials and devices on the scale
of atoms and molecules. It encompasses science and technology that manufactures materials
of great help to the improvement of various areas of society especially health, environment,
energy, electronics, food, water, and agriculture.
The Nanoparticles
Uses and Applications of Nanotechnologies
Because of their unique properties and structures, nanoparticles have a wide array of uses and
applications. They can be used in medicine, energy, environment, agriculture, food security,
communication, and other fields. These are some examples:
