Future Technology........ Nanotechology

[Md.Fakhrul Islam]

Technology at the nano level, or nanotechnology, allows for unbelievable precision and a way to copy the work of nature at its most basic functioning, but just how small is a nano? According to the National Nanotechnology Initiative, a sheet of paper is 100,000 nanometers thick and there are 25.4 million nanos in 1 inch. A nanometer is one-billionth of a meter.

How is this impacting technology and the future? In just about every field, nanotechnology is being used for innovations in engineering, medical devices, imaging, computing and many more. Nano medicine is one area experiencing rapid and dramatic growth. Because many illnesses and disorders in the body take place at the cellular level and grow as ruled by the formation of genetic makeup, nanotechnology has the capability to treat at the very root of the condition, rather than after it's fully spread throughout the body. It can be both preventative and curative because treatment reaches the narrowest and most minuscule centers of control. Neurosurgery and gene therapy are just two areas within nanomed that are particularly well-suited for nano tools and technology.

Much of the work being done today that carries the name 'nanotechnology' is not nanotechnology in the original meaning of the word. Nanotechnology, in its traditional sense, means building things from the bottom up, with atomic precision. This theoretical capability was envisioned as early as 1959 by the renowned physicist Richard Feynman.

   '' I want to build a billion tiny factories, models of each other, which are manufacturing simultaneously. . . The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big." — Richard Feynman, Nobel Prize winner in physics
