What could nanotechnology bring to humanity?

What could nanotechnology bring to humanity? Probably, in recent years, many have heard this now fashionable word - nanotechnology. But hardly anyone who uses this word in conversation, able to clearly explain what it is. Many tipped Nanotechnology great future. Many people genuinely fear them, suggesting that nanotechnology could be the genie, released from the bottle. So, what is it - nanotechnology, and how they can help humanity? What they have us - a bright future or global threat?

  What is nanotechnology? Nanotechnology can be safely called a fantasy that became reality. Mankind has learned to manage the atoms. Modern technologies allow folding of the atoms of different devices and mechanisms that can not be seen with the naked eye. Science, which incorporates the latest advances in the study nanoworld, which includes a variety of disciplines such as biology, physics, chemistry, and is Nanotechnology .
Everyone knows that capping translated from the Greek word meaning "dwarf". A nanometer (nm) - is negligible, amounting to one-billionth of a meter. Nanotechnology works with objects whose dimensions range from 0.1 to 100 nm.

  Nanotechnology - the first steps. For the first time, back in 400 BC, thought of the smallest particles that make up the substance, the Greek philosopher Democritus. It was he who introduced the concept of 11,111,114. atom [/i] That means 11,111,114. neraskalyvaemy [/i] . In 1905, the great Einstein suggested that the size of sugar molecules is 1 nanometer. In 1931, German physicists have created an electron microscope, which is finally allowed to see the man nanostructure. In 1974, Japanese physicist Norio Taniguchi offers include mechanisms for measuring less than one micron, the word Nanotechnology . In 1981, Germany's physicists have created a microscope with which could consider the individual atoms. In 1986, the futurist Erk Drexler publishes a book, which predicts a great future for nanotechnology. Since then nanotehnogii received wide publicity. In 1998, Dutch physicist Seez Dekker is already practical application nanoobjects. It creates a transistor based on nanotechnology.
As can be seen as a science of nanotechnology are developing very rapidly. It is difficult to suggest what the prospects opening up before mankind by nanotechnology.

  Practical application . Nanotechnology is currently not yet found wide practical application. But I assure you, this is a matter of time. In the very near future we will use things produced with the help of nanotechnology. It is already possible to talk about products that have passed the way from the laboratory to the factory. Modern products made using nanotechnology, have in their composition of carbon nanotubes, which in turn are the basis for other nanoproducts produced at this time. What are carbon nanotubes? They were discovered in 1991 and represent the extended cylindrical structures with diameters from one to several tens of nanometers and a length of several centimeters. It turned out that they have amazing properties. Thanks to these properties, they found many uses. For example, they can be used in electronics, computer industry, medicine and even in the industry.

How can I apply nanotechnology in medicine? Due to its properties of nanomaterials can be used to replace human tissue. It turns out the body's cells, recognize these materials as their own. Even now, progress has been made in the manufacture of nanomaterial that can simulate the bone tissue. The microscopic size of nanomaterials can be used as capsules, through which the delivery of medicines in the right places of the body. They can be used as a filter body fluids from harmful substances and viruses. Now more common miniature devices placed inside the body for diagnostic and therapeutic purposes.

  Prospects of Nanotechnology . A bit of fantasy.
In medicine, planned to create molecular robots that can heal the body, while inside it. Why? Very convenient.
In industry. Consumer goods can be created directly from the atoms and molecules. By change of place of atoms and molecules can be manufactured any item!
In biology, perhaps "introduction" in the various organisms at the atomic level. What does this give us? Restoration of extinct species of animals and even the creation of new creatures, "biorobots.
And, finally, in gerontology. Immortality will be possible by introducing into the organism of molecular robots, which will purify the body and eliminate the disease at the very beginning of their inception.
