Nanocomputing Nanocomputing describes computing that uses extremely small, or nanoscale, devices (one nanometer [nm] is one billionth of a meter). In 2001, state-of-the-art electronic devices could be as small as about 100 nm, which is about the same...

Molecular computing is the science of using individual molecules to build computer programs. Instead of running software on a traditional computer, some scientists are now trying to replace the silicon chip with test tubes, liquids, and even living...

In nanochemistry, the rules of bonding are extended from atoms and molecules to larger objects having the dimension of from 1 to 100 nanometers, where one nanometer is one-billionth of a meter. In this regime, new chemical and physical properties...

Nanotechnology refers to the construction and use of atomic machines—functioning consortia of atoms that are less than about 1,000 nanometers in size. A nanometer is one billionth of a meter. The technology is relevant to computer science as it...

Nanotechnology refers broadly to a field of applied science and technology whose unifying theme is the control of matter on the atomic and molecular scale, normally 1 to 100 nanometers, and the fabrication of devices within that size range. It is a...

The use of subatomic materials as microscopic building blocks for thousands of consumer products has turned into a big business so quickly that few are monitoring the so-called nanotechnology's effects on health and the environment.So Berkeley intends to be the first city to step into...

Food, drugs, medical devices and cosmetics that contain minuscule engineered particles don't necessarily need special labeling to alert consumers, a federal task force recommends.The Food and Drug Administration should consider each product using nanotechnology on a case-by-case basis, an agency task force said in a...

Tighter regulation and control is needed to ensure the safety of nanotechnology _ the manufacture of atomic particles _ the U.N. said Monday.In its annual report of the global environment, the U.N.'s Environment Program said "swift action" was needed by policy-makers to properly evaluate the...

A pair of tech giants are bringing what once was science fiction into real life. They're taking nanotech to computer chips. IBM IBM and Hewlett-Packard HPQ are both unveiling ways of using nanotechnology in the chipmaking process this week. The advances point 15 the key...

Essay describes the physics involved in nanotechnology and many of its applicaions.

This essay explains the implications that nanotechnology will eventually have on the world of cancer.
