Transcript of Nanotechnology
European Union: 1.2 Billion USD
Japan: 750 Million USD How small is "nano"? Nano in nanotechnology usually refers to any object that ranges from 1 to 100 nanometers. How small is a nanometer? In the International System of Units (SI Units), the prefix "nano" refers to one-billionth, meaning that a nanometer is one-billionth of a meter. Need a better picture of that? Mount Everest, the highest mountain on Earth, is 8,850 meters high. The lenght of a soccer pitch is 120 meters. An ant is 4 millimeters long A raindrop is 2.5 millimeters in diameter. A bacterium is about 2.5 micrometers long. And so, we reach DNA, our genetic blueprint. DNA is 2 billionths of a meter, or 2 nanometers. When did nanotechnology start? Although the start of nanotechnology was on the early ´80s by Dr. K. Eric Dexler, the concept of nanotech has been around for decades past that. Nanotech: Making Smaller, Better With many advances being made in nanotechnology, most electronics are now becoming smaller, but more efficient and lasting. Stonger building material is also being made. Concerns: Tests with lab rats have shown that inhalation of nano particles have an effect on the central nervous system proven to be as dangerous as cancer.
Small microstructures made that are inhaled can go tu lungs and have the same effect as asbestos.

The advances it has given us so far are just the tip of the iceberg. Better and more efficient constructions and electronics are to come.
