Nanotechnology definition

nănə-tĕk-nŏlə-jē
Nanotechnology is the managing matter at a very small scale. Specifically, it is controlling matter at the atomic level. Nanotechnology refers to structures or matter that are one hundred nanometers large or smaller. The actual field is quite assorted, and includes both manmade objects and natural objects that are manipulated.

Nanotechnology is currently affecting almost every part of your daily life. You are using products that have been created by nanotechnology without even realizing it. Nanotechnology products are used in metals, polymers, ceramics, and biomaterials. Nanotechnology has already changed how products are manufactured.

As of 2010, there were approximately eight hundred nanotech products that are available to the public. The field is growing in size, and every week there are approximately three to five new nanotech products that are developed. Some of the products that are affected by nanotech include:
  • Cosmetics.
  • Food.
  • Sunscreen.
  • Food packaging material.
  • Clothing.
  • Disinfectants.
  • Household appliances.
  • Paints.
  • Furniture varnishes.

There are hundreds of nanotechnology companies; but, it’s useful to know a couple of the companies to begin to understand the field:
  • NanoStellar is a company that creates a nano-composite catalyst that is used in catalytic converters.
  • CO2 Solution is a company that produces an enzyme for removal of carbon dioxide from smoke stacks.
  • Altimate EnviroCare creates a spray on film that uses titanium oxide nanopartices. This film kills bacteria and eliminates odor.

In 1959, Richard Feynman became the first individual to give a lecture about the concepts involved in nanotechnology. He gave the talk at the American Physical Society at Caltech. The talk specifically examined how individuals might be able to manipulate atoms and molecules into smaller structures. The talk was well received, and it introduced the idea to the science world. In 1974, Norio Taniguchi coined the term “nanotechnology” to refer to this new and developing field.

The two major techniques that are used in the field are:
  • Bottom up technique - materials are created using molecules. These molecules assemble themselves according to the chemical rules of molecular recognition.
  • Top down approach - nano-objects are created using larger materials. The top-down approach does not use atomic control.

The building of very small machines. Nanotechnology involves manipulating matter at the atomic scale, resulting in faster, more powerful technology that uses smaller parts. A nanometer, which is a billionth of a meter, is only about three to five atoms wide. In early 2003, some companies were working on creating a manufacturing technology for computer chips that were 90 nanometers across, which is 30 percent smaller than the 130-nanometer computer chip technology that was common in 2002.

A number of different technologies helped advance the field of nanotechnology. Two microscopes greatly helped the development of nanotechnology: the Atomic Force Microscope and the Scanning Tunneling Microscope. The abilities of these microscopes were key to being able to develop and manipulate very small structures. In the late seventies, the scanning acoustic microscope was developed by Calvin Quate. This microscope made it easier for scientists to manipulate different nanostructures using sound. As the field of nanotechnology grew, scientists invented a number of techniques using other technologies that improved the study of nanotechnology including:
  • Optical lithography.
  • X-ray lithography.
  • Dip pen nanolithogtaphy.
  • Electron beam lithography.
