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.

Notes on 2014 Foresight nanotechnology conference

Posted by Jim Lewis on March 7th, 2014

A “sense of energy, momentum, and collegiality throughout the weekend” united attendees hearing about the integration of nano-engineered devices and materials into more complex systems, and the integration of nanoscale technologies into diverse applications.

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

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 [...]
