Nanotechnology A Radical Technology for the Future

  Nanotechnology is a study, which deals with the development and manipulation of matter, materials, and structures that are sized between 1 to 100 nanometers. One nanometer is equal to one billionth of a meter. Though nanotechnology can be considered as recent technological advancement, the groundwork for this technology was formulated and conceptualized in the early 1980s. In simple terms, a comparative size of a nanometer to a meter is the same as that of a marble when compared to the size of the earth.

The groundwork laid for nanotechnology was further enhanced by the invention of scanning tunneling microscope in 1981 and the discovery of fullerenes in 1985. The invention of the scanning tunneling microscope really triggered the study of nanotechnology. The scanning tunneling microscope enables the viewing of imaging surfaces at the atomic level at a good resolution of 0.1 nanometer and a 0.01 nanometer depth resolutions. At these resolutions, scientists were able to view individual atoms within materials and manipulate them. Another invention which aided the development of nanotechnology was the birth of cluster science and the invention of fullerenes. Fullerenes are molecules composed entirely of carbon, in the form of a hollow sphere, ellipsoid or tube.

The credit to the formulation and conceptualization of nanotechnology is shared by a number of scientists. The speech given by Richard Feynman in the late 1950s is considered to be the inspiration for the development of nanotechnology. Norio Taniguchi coined and used the term nano-technology in 1974 to describe processes such as thin film deposition and ion beam milling. In the 1980s, Eric Drexler took steps to promote the technological ideas of nano-scale phenomena and nanomaterials through speeches and books.

Nanotechnology can be further subdivided into various other related categories such as nanomaterials, nanomedicine, molecular self-assembly, and nanoelectronics. All these categories are subject to research and the early results are positive. Nanotechnology also deals with conventional device physics, and also implicates the application of fields such as surface science, organic chemistry, molecular biology, semiconductor physics, and microfabrication, among others.

Nanotechnology applications are used across various industries such as medicine, environment, energy, communication, heavy industry, and consumer goods. In the medicine and pharmaceutical industry, the technology is used for diagnostics, drug delivery, and tissue engineering. In the environment related industry, it is used in nanofiltration, nanotechnology, and other environmental applications. In the energy industry, nanotechnology is used to reduce energy consumption, increase energy production, and clean nuclear waste. In the information and communication space, it is used in the development of memory storage devices, novel semiconductor devices, novel optoelectronic devices, displays, and quantum computers.

For all those on the lookout for an engrossing field of study, nanotechnology is your prime option and it will certainly prove to be a noteworthy career option. To know more about nanotechnology and the related fields, get into a public library and ask the librarian for some famous books on nanotechnology. If you could afford to get a Cheap Internet connection with minimal download speeds, you could research and read through e-books and articles on nanotechnology, on the other hand, you can also gain access to nanotechnology journals and comment on related blogs and forums.

As with all new technologies, there is a sort of skepticism among people when trusting this new technology, but there will be a day when this technology will certainly answer all the critics. Akin to the dot-com bubble in the late 1990s, it is certain that there will be another technology bubble, this time relating to the field of nanotechnology. With nanotechnology catering almost all the vital industrial sectors, it is sure to dominate the marketplace with its innovations in the near future.
