A Breakthrough in 3D Imaging by EM Alone

Posted by Stephanie C on October 8th, 2014

The need for improved imaging and characterization on the nanoscale was emphasized in the 2007 Roadmap and again at the 2013 Foresight Conference on Atomic Precision. We noted last year a new advancement in atomic-scale resolution of 10-nm platinum particles, requiring multiple imaging techniques in combination, and recently the marked improvement in optical imaging for [...]

Tailoring the shapes of organic molecules by assembly-line synthesis

Posted by Jim Lewis on October 3rd, 2014

To emulate the process by which nature assembles complex organic molecules by passing subunits through a series of enzyme domains, UK chemists developed a procedure to elongate a boronic ester by using a reagent that inserts into carbon-boron bonds with precise control of molecular configuration.

Nanomanufacturing grants available from US National Science Foundation

Posted by Jim Lewis on September 27th, 2014

The US NSF has announced a program to support fundamental research leading to complex nanosystems.

DNA nanotechnology and the atoms to micrometer nanofabrication gap

Posted by Jim Lewis on September 26th, 2014

A new DARPA program seeks to bridge the gap from atoms to macroscale product manufacture in two steps, the first of which is from atoms to micrometer-scale feedstocks. DNA origami may be part of the solution.

Scaffolded DNA origami improvements advance DNA nanotechnology

Posted by Jim Lewis on September 25th, 2014

A 10-fold larger breadboard and 350-fold lower DNA synthesis costs make DNA origami a more useful stepping-stone toward atomically precise manufacturing.

Proof of principle for nanoscale assembly line

Posted by Jim Lewis on September 2nd, 2014

Swiss researchers have used biomolecular shuttles to capture molecular building blocks from solution and transport them across fluid flow boundaries to be further manipulated in a subsequent chamber.

DARPA announces new program on nanoscale assembly and integration

Posted by Jim Lewis on September 1st, 2014

Register by Sept. 5 to attend a Proposers Day webinar on either Sept. 9 or 11 to learn the technical objectives of DARPA’s new “Atoms to product: Aiming to make nanoscale benefits life-sized” program.

What kind of nanomachines will advanced nanotechnology use?

Posted by Jim Lewis on August 31st, 2014

An interview with UK nanotechnologist Richard Jones argues that the surest and most efficient path to advanced nanomachine function will incorporate or mimic biomolecular nanomachinery rather than scaled down rigid conventional machinery.

Seeing and touching a single synthetic molecular machine

Posted by Jim Lewis on August 24th, 2014

Attaching a 200-nm-diameter magnetic bead to a 1-nm diameter synthetic molecular machine allowed optical visualization of the motion of the machine and manipulation with a magnetic tweezers.

Expanded DNA alphabet provides more options for nanotechnology

Posted by Jim Lewis on May 14th, 2014

A bacterium has been engineered to stably propagate a DNA written with six letters instead of the usual four, greatly expanding the number of amino acids, both natural and synthetic, that can be genetically encoded. Further work could lead to novel proteins incorporating these additional amino acids, and from there to novel materials, devices, and machines.

A bird's-eye view of half a century of nanotechnology
