Do tiniest particles put us at risk?
As nanoparticles enter our lives, stepped-up research urged on potential threats
Life changing factories
Nanotechnology is an umbrella term that covers many areas of research dealing with objects that are measured in nanometers.
A nanometer (nm) is a billionth of a meter, or a millionth of a millimeter.
In the next 50 years, machines will get increasingly smaller - so small that thousands of these tiny machines would fit into the period at the end of this sentence.
Within a few decades, we will use these nanomachines to manufacture consumer goods at the molecular level, piecing together one atom or molecule at a time to make baseballs, telephones and cars.
This is the goal of nanotechnology.
As televisions, airplanes and computers revolutionized the world in the last century, scientists claim that nanotechnology will have an even more profound effect on the next century.
