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

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

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… Continue reading New Report: Nano-solutions for the 21st century

Open Access journals for nanotechnology and other topics

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

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… Continue reading Advanced technologies by design

2013 conference video: Mechanical Atom Manipulation

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

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

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

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

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

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