Featured in About Nanotechnology
The major focus of nanotechnology is to view, measure and even manipulate materials at the molecular or atomic scale.
In “nanomaterials,” the size and shape of the very small domains that compose the bulk material affect its properties.
Properties of materials at the nanoscale are different in many cases from the properties of materials observed in other scales.

Nanotechnology also involves biology, several disciplines of engineering, material science, and medicine. Anywhere molecules and atoms are concerned, nanotechnology can potentially play a role.
Many potential applications of nanotechnologyhave social implications. Enhanced computing and sensing, for example, can be very useful objectives in the right hands – they can improve human welfare, and support healthcare, safety, information exchange, and entertainment. However, in the wrong hands, these technologies also enable more effective surveillance and analysis of communication that may be detrimental to freedom and human rights.
History of Nanotechnology As is the case with many other disciplines, applications of nanotechnology (for example, in making steel and creating paintings) were in use centuries before the field was formally defined. Early contributors to the field include James Clark Maxwell (Scottish physicist and mathematician, 1831-1879) and Richard Adolf Zsigmondy (Austrian-German chemist, 1865-1929). Zsigmondy studied colloids (chemical mixtures where one substance…
The Future of Nanotechnology The future of nanotechnology has been a subject of many scientific and nonscientific speculations, including several doomsday visions in popular culture that predicted self-replicating nano particles taking part in massive assaults on humanity and the environment. An example of such scenario is given in Michael Crichton popular novel Prey, where “grey goo”…
