IBM Researchers Demonstrate New Method for Rapid Molecule Sortin. IBM researchers have demonstrated a new nanoscale method that both rapidly separates very small numbers of molecules and also delivers them precisely onto surfaces with unprecedented control. When fully developed, the new technique has the potential to improve such diverse applications as medical lab tests and future nanoelectronic circuit manufacturing.
The method is based on the atomic force microscope (AFM), an instrument invented by an IBM Nobel Laureate 20 years ago that performs nanoscale operations using a tiny cantilever with a cone-shaped tip at its end. When an electrical field is applied to the tip, molecules will slide up or down its surface at characteristic speeds. By modifying the tip's surface and varying the strength and duration of the electric field, different molecular species can be separated from each other within a few milliseconds, more than 1,000 times faster than today's methods. IBM is exploring options for commercializing this invention.

Eric Drexler, Josh Hall, Ninad Sathaye and Mark Sims includes 11 components totalling 25,374 atoms. The animations below have been created from simulation results using NanoEngineer-1 Alpha 7, taking just over 370 hours to complete on a Dell laptop running WindowsXP. It is the largest model ever simulated with NanoEngineer-1. More information about this model is coming soon. Tags: nanotechnology nanotech nano science technology ethics weblog blog.

Contents:1. 1. The utility of a new technology depends on many factors, including the difficulty of development and the ease and cost of use. This paper builds on previous proposals to describe an architecture for combining large numbers of programmable mechanochemical fabricators into a manufacturing system, or nanofactory, capable of producing a wide range of human-scale products. This exploration can provide a basis for estimating the practical value and difficulty of developing a nanofactory. The paper is arranged in several sections. 2. In order to create useful products with molecular manufacturing, several steps are required. 2.1. 2.2. 2.3. Nanomateriaux.

An Invitation to Enter a New Field of Physics by Richard P. Feynman This transcript of the classic talk that Richard Feynman gave on December 29th 1959 at the annual meeting of the American Physical Society at the California Institute of Technology (Caltech) was first published in Caltech Engineering and Science, Volume 23:5, February 1960, pp 22-36.

I imagine experimental physicists must often look with envy at men like Kamerlingh Onnes, who discovered a field like low temperature, which seems to be bottomless and in which one can go down and down. I would like to describe a field, in which little has been done, but in which an enormous amount can be done in principle. What I want to talk about is the problem of manipulating and controlling things on a small scale. As soon as I mention this, people tell me about miniaturization, and how far it has progressed today.
