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.

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.

Recent cases of 'accessible' high-tech: Open source chips & Origami robots

Posted by Stephanie C on August 22nd, 2014

Nanotech promises more commonplace access to advanced technology as material and fabrication costs fall and traditional barriers to innovation are removed. Examples are already being seen globally: more access to laptops and cell phones in developing countries, desktop 3D printers, a surge in establishment of shared-use research facilities, etc. A couple recent cases getting attention [...]

Tunable Assembly of Nanoparticles for (Photovoltaic) Devices

Posted by Stephanie C on August 13th, 2014

Photovoltaics are an interesting case where atomic precision is not necessary to achieve potentially dramatic global impacts. Even an “ok efficiency” device that is easy to manufacture with reduced environmental hazard could have significant beneficial effects on energy resources and on device fabrication processes (which could, in turn, contribute to developments toward APM). The struggle [...]

The NNI Debate of 2014

Posted by Stephanie C on July 11th, 2014

Just when it seemed like debate over the National Nanotechnology Initiative was a thing of the past (see Foresight’s disappointment in 2008 here), disagreements regarding re-authorization and budget cuts are prompting politicians and researchers to take a detailed look at what the program supports and what it is achieving. Witnesses to the House Research Subcommittee [...]

The atomically precise manufacture of quantum dots

Posted by Jim Lewis on July 5th, 2014

Using an STM to precisely position indium adatoms on an indium arsenide surface, nanotechnologists have created a series of atomically precise quantum dots, and joined them with atomic precision to make quantum dot molecules, opening new avenues to construct practical quantum devices for computing and other applications.
