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 [...]

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
