A tutorial review addresses the distinction between the many simple artificial molecular devices that are currently available and truly effective artificial molecular machines that would mimic the ubiquitous molecular machines present in living systems.
In a lecture at Oxford Eric Drexler argued that atomically precise manufacturing will be the next great revolution in the material basis of civilization, and discussed how we can establish reliable knowledge about key aspects of such technologies.
Varying the length of the DNA used to connect the nanoparticles provides for a wide variety of nanoparticle sizes and crystal symmetries.
An algorithm helps design peptides that will self-assemble on a given surface to produce a supramolecular structure of desired geometry.

New computational method screens for small molecules that bind to RNA molecules that move through a variety of conformations.
Does the recent discovery that quantum tunneling controls a chemical reaction of a carbene complicate theoretical studies of nanotechnology, especially of diamond mechanosynthesis?
Computational studies show that small diamond structures of the type that might serve as nanoparts in diamondoid molecular machinery are structurally stable.
A biochemical circuit built from 74 small DNA molecules demonstrates an approach that may enable embedded control of molecular devices.
The interactions of xenon atoms with a nanoelectromechanical system have now been measured to characterize the statistical noise caused by atomic fluctuations.
We are proud to announce our final conference program for Foresight@Google‘s 25th Anniversary Conference Celebration, held June 25-26 in Mountain View, CA. For $50 off registration use code: NANODOT This weekend – full of plenary talks, panels, and breakout sessions – is a unique opportunity to be stimulated, enlightened and inspired by direct interaction with [...]
A Monte-Carlo simulation shows that a simple self-replicating RNA-like molecule in a specific protective environment could evolve the ability to translate a genetic code to produce peptides.
Midnight tonight Pacific time is the deadline for the early registration rate on Foresight@Google, our 25th Anniversary Conference and Celebration. Check it out here: http://foresight.org/reunion Past participants have said: “This is mind candy for my soul. Having attended for two years now, this event stands alone in my mind as an opportunity to explore new horizons, [...]
New software for scaffolded DNA origami makes it easier to predict what shape will result from a given DNA template.
Combined computational and experimental study shows molecules walking, hopping and flying across a surface; may lead to controlling molecular motion.
MIT scientists have devised much more efficient procedures for modeling protein folding in order to be able to model the folding of the flood of proteins sequences made available by modern genome sequencing methods.
A step toward advanced nanotechnology has been achieved by using attachment to a surface and confinement by surrounding molecules to make two molecules react to form a product that would not form if they were free to react in solution.
Computational work links optically-induced molecular shape change to change in DNA structure to extract useful work.
Sometimes the behavior of electrons in nanostructures can be modelled using classical laws of motion, while at other times more computationally challenging quantum methods are necessary to obtain useful results. Christopher W. Ince of the Nanotechnology Research Foundation writes with news of a new method to distinguish classical from quantum behavior in electrons: Researchers from [...]
