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 [...]

2013 conference video: Mechanical Atom Manipulation

Posted by Jim Lewis on December 2nd, 2013

At the 2013 Conference Philip Moriarty presented non-contact Atomic Force Microscope experiments demonstrating mechanical toggling of silicon dimers on a silicon surface. The crucial role of precise control of probe tip structure was emphasized.

Nanotrain uses molecular motors and DNA nanotechnology controls

Posted by Jim Lewis on December 2nd, 2013

Using DNA nanotechnology to control and organize molecular motors and the molecular tracks that they run on, a novel nanotrain transports molecular cargos tens of micrometers.

Upcoming Book Explores Nanomedical Device and Systems Design

Posted by Jim Lewis on November 21st, 2013

A new book by Frank Boehm explores the challenges, possibilities, and visions of nanomedical device and systems design.

Graphene nanoribbon senses passage of individual bases of DNA

Posted by Jim Lewis on November 19th, 2013

A nanoribbon transistor no thicker than the distance between adjacent DNA bases provides high resolution sensing of DNA passage through nanopores, perhaps leading eventually to rapid DNA sequencing.

Nanoparticle therapy for incurable brain cancer effective in mice

Posted by Jim Lewis on November 15th, 2013

Gold nanoparticles densely coated with RNA molecules intended to silence a gene essential for an incurable brain cancer proved effective in mice engrafted with human glioblastoma multiforme tumor.

Adding more chemical interactions to DNA nanotechnology

Posted by Jim Lewis on October 24th, 2013

Modifying DNA strands with lipid-like molecules opens more possibilities for designing DNA structures for drug delivery and other purposes.

TEDx talk: "Transforming the Material Basis of Civilization"

Posted by Stephanie C on October 14th, 2013

Eric Drexler’s TEDx talk entitled “A Future of Radical Abundance: Transforming the Material Basis of Civilization” is available for viewing on Youtube as well as on Drexler’s blog site. As described by the Oxford Martin School, where Drexler is a scholar with the Programme on the Impacts of Future Technology: Dr. Eric Drexler’s talk from [...]

Carbyne: the strongest, stiffest carbon chain

Posted by Stephanie C on October 11th, 2013

Carbyne – a straight line of carbon atoms linked by double bonds or by alternating single and triple bonds — is the next stiff, carbon-based structure with unusual and desirable properties. It has been observed under limited natural and experimental conditions, is expected to be difficult to synthesize and store, and now has been theoretically [...]

Nanotubes aren't stiff if they aren't straight

Posted by Stephanie C on October 3rd, 2013

Materials scientists have pursued the question of why vertically aligned carbon nanotube forests show much lower modulus values than expected. Now researchers from Georgia Tech have found that the nanotubes they fabricate contain kinks that dramatically diminish modulus value. In other words, the nanotubes are not straight; therefore, they are not stiff. The government-funded research [...]

Foresight Invitational Workshop: Nanotechnology for Developing Countries

Posted by Jim Lewis on September 30th, 2013

An invitational workshop to address the opportunities and challenges of nanotechnology for developing countries will be held in parallel with Foresight’s open nanotechnology conference “The Integration Conference”.

Computational design of protein-small molecule interactions

Posted by Jim Lewis on September 26th, 2013

A major advance in the computational design of proteins that bind tightly to specific small molecules will facilitate several technologies, possibly including the development of atomically precise manufacturing.

Building a hub for nanotech advancement

Posted by Stephanie C on September 17th, 2013

Nanotechnology draws from physics, chemistry, engineering, computation, etc., and this multi-disciplinary nature has served as a major speed bump in achievement of envisioned nanotech goals. There has been substantial concern that the U.S. is lagging behind other countries in nanotech R&D. Now researchers, companies, and politicians are coming together to create a much-needed physical hub [...]

Circuits of graphitic nanoribbons grown from aligned DNA templates

Posted by Jim Lewis on September 17th, 2013

How complex could circuits be made using precisely positioned DNA nanostructures as templates to grow graphene nanoribbons?

Precise mechanical manipulation of individual long DNA molecules

Posted by Jim Lewis on September 12th, 2013

“Molecular threading”, a nanotechnology developed by Halcyon Molecular and now owned by Aeon Biowares, enables precise placement of individual long molecules of DNA, either for sequencing or for nanofabrication of novel DNA nanostructures.
