The nanometer is so small, that it is hard to say what the scale is. You can for example say that a human hair is shared 80,000 times longitudinally. The human eye is cable to see the nanometer, when we talk about 20,000mm.

A nanometer is called for the 21st century’s technology, the visions of what the human in the future can free itself of the known structures to be able to determine a desired material, shape and features.

From physics we know that this is how the atoms in a substance are arranged to make the characteristics of a substance, for example, graphite and diamond made of the same element namely carbon, but the atoms' location is different, and it gives the two substances different properties. Similarly applied nanotechnology. By means of the advanced microscopes, it has become possible rearranging atoms and give the new substances these very special properties.If you ask the 'normal' people about what nanotechnology is, they will probably say that it is some kind of science fiction, supernatural creatures and robots. But it is a completely wrong perspective to have, for nanotechnology may be the world's lifeboat as nanotechnology can help to reduce the consumption of the more dangerous CO2.
