Building biological molecular machines as an open source path to advanced nanotechnology

Posted by Jim Lewis on July 24th, 2014

B.R.AI.N.S., Berkeley BioLabs, and Foresight Institute to build an open source biological parts repository and design and distribute a line of “How-to Build Biological Machines” educational kits.

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.

Lipid coat protects DNA nanorobot from immune attack

Posted by Jim Lewis on July 5th, 2014

Enveloped DNA nanostructures were developed to escape attacks from nucleases and the immune system, opening a path to ever more sophisticated DNA nanomedical devices.

Robust triangular RNA brick adds to RNA nanotechnology toolkit

Posted by Jim Lewis on June 24th, 2014

The complex molecular recognition code of RNA offers RNA nanotechnology a greater variety of 3D structures and functions than are present in DNA nanotechnology, but the RNA structures can be fragile. New RNA triangles that resist boiling solve this problem.

DNA nanotechnology replicates enzyme cascade

Posted by Jim Lewis on June 4th, 2014

A swinging DNA arm added to a DNA scaffold makes it possible for two enzymes attached to the scaffold to complete a coupled chemical reaction.

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

Posted by Jim Lewis on May 7th, 2014

Reviewing Eric Drexler’s Radical Abundance, Phil Bowermaster provides an informed and insightful overview of the controversies that greeted the proposal for a nanotechnology aimed at developing a practical technology for atomically precise manufacturing. Along the way he shows how Drexler’s outlook evolved from 1986 to 2013.

Physicists suppress 'stiction' force that bedevils microscale machinery

Posted by Jim Lewis on April 19th, 2014

A possible top-down path to atomically precise manufacturing that passes through microscale machinery might be rendered easier because of recent progress in suppressing the Casimir force, which contributes to the ‘stiction’ problem often encountered with microelectromechanical systems.

US government report highlights flaws in US nanotechnology effort

Posted by Jim Lewis on April 1st, 2014

The concern of the US GAO for a gap in nanomanufacturing is well-placed, but it is only half of the problem with the limited US vision of the impact of nanotechnology on the future world economy.

Bigger, stiffer, roomier molecular cages from structural DNA nanotechnology

Posted by Jim Lewis on March 29th, 2014

Using struts made of DNA to stiffen polyhedral corners, scientists have build rigid DNA cages an order of magnitude larger than previous DNA nanostructures, and only one order of magnitude smaller than bacterial cells.

Chemists provide new tool for nanotechnology-modifying the right carbon atom

Posted by Jim Lewis on March 27th, 2014

A new tool to chemically modify one specific carbon atom among several chemically very similar ones will facilitate building larger, more complex molecules for drug discovery and for nanotechnology.

Will crowdsourced RNA designs advance nanotechnology?

Posted by Jim Lewis on March 6th, 2014

A very large community of online gamers has consistently produced RNA designs that outperform the best design algorithms by a large margin. Can online gamers designing RNA, protein, and other molecules contribute to the development of atomically precise manufacturing?

Better nanoswitches by integrating double and triple strand DNA

Posted by Jim Lewis on January 28th, 2014

A DNA clamp engineered for higher specificity and higher affinity may improve cancer diagnosis and treatment and may also mean better control over building nanomachines.

Integrating DNA nanotechnology and RNA to transport nanoparticles along nanotubes

Posted by Jim Lewis on January 21st, 2014

A possible forerunner to a future molecular assembly line uses an artificial DNA motor to transport an artificial nanoparticle along a carbon nanotube track.

RNA nanotechnology - fewer structures in living cells than in test tubes

Posted by Jim Lewis on January 14th, 2014

A study of RNA structures actually present in cells reveals that cells spend energy restricting thermodynamically driven RNA folding so that fewer RNA structures are found in cells than in test tubes.

New Report: Nano-solutions for the 21st century

Posted by Stephanie C on December 20th, 2013

A recently released technology report titled Nano-solutions for the 21st century outlines nanotech-based solutions to global challenges. Several years in the making, the report was co-authored by Dennis Pamlin, Research Fellow at the Chinese Academy of Social Sciences Research Center for Sustainable Development (RCSD web site currently in Chinese only), and Eric Drexler, Academic Visitor [...]

Open Access journals for nanotechnology and other topics

Posted by Jim Lewis on December 19th, 2013

A collection of open access journals on a variety of topics provides a very useful entry point to the rapidly growing collection of scientific, technical, and scholarly research that is not hidden behind pay walls.

Advanced technologies by design

Posted by Stephanie C on December 16th, 2013

Design and prediction are integral to Atomically Precise Manufacturing and its development. This is in part because fully functional APM can be readily explored computationally today, to levels of precision that cannot be experimentally developed today. In such a context, design is not just a resource but an approach. With rapidly expanding computational power, examples [...]
