Nanotechnology

picture of nanotechnologyAmong all the technological wonders of modernity, there is one that, in perspective, can literally revolutionize reality. During the recent two centuries, there have been several such discoveries: electricity, radio waves, flight, nuclear energy, the Internet, and others. But today humanity stands on the edge of something completely new – nanotechnology.

To start the explanation of nanotechnology in a proper way, let us figure out what is this “nano-” part of the word. “Nano-” is a prefix used in the metric system, meaning one billionth part of something; so, nanometer, a standard measurement unit, is a 0,000000001 part of a meter. In order to be able to imagine how small this value is, let us refer to examples. One inch is 25,400,000 nanometers. Even a more illustrative example: a sheet of regular office A4 paper is 100,000 nanometers thick (Nano.gov). Human hair is about 80,000 nanometers thick (Nanowerk.com). Generally speaking, “nano-” in “nanotechnology” means “very small, tiny.”

So, in this case, what exactly is nanotechnology? According to the U.S. National Nanotechnology Initiative, nanotechnology implies the ability to understand and control matter at dimensions between approximately from 100 up to one nanometers; it also involves imaging, measuring, modeling, and manipulating matter at the estimated length scale (Nanowerk.com). At the nanoscale, matter possesses unique properties; properties of materials behave under atomic and molecular rules, and this is why nanotechnology is so perspective: researchers can gain control over these unique properties to create new tools and products in areas of science and engineering (nnin.org). For example, nanotechnology allows to construct materials and structures at an atomic scale; it means that scientists can actually “build” materials from atoms and molecules.

Nanotechnology is still in the process of development, but nevertheless it can already surprise humanity with wonders that were impossible several decades ago. For example, there exist special carbon nanotubes that are able to turn into an artificial muscle; there is a 3D printer that can print new cancer drugs; there already exist self-healing materials such as concrete that fills in its own cracks to ship hulls that knit back together; there were created viruses that convert pressure into electrical energy, and so on. These and other inventions are just the beginning of a new technological era (io9.com).

Nanotechnology is a relatively new branch of science which can revolutionize the reality we live in today. Nanotechnology operates with matter at dimensions between one to one hundred nanometers. This allows scientists to gain control over the unique properties that matter at such a small scale possesses. Self-healing materials, artificial muscle, and other wonderful inventions are just the beginning of the new era of technology.
