Novel RNA structural motifs expand tool kit for RNA nanotechnology

New computational methods to explore the rapidly expanding collection of high resolution three-dimensional RNA structures reveal new RNA structural motifs, identifying additional building blocks for complex RNA nanostructures.

Nanotechnology, DNA sequencing, and personalized medicine

Artist’s conception of a nanopore drilled into a layer of graphene to speed up DNA sequencing. One of the greatest promises of near-term nanotechnoloogy is cheaper DNA sequencing to speed the development of personalized medicine. There are not only genetic differences between different patients, but also genetic differences between, for example, different cancers of the… Continue reading Nanotechnology, DNA sequencing, and personalized medicine

DNA motor navigates network of DNA tracks

Scientists at Kyoto University and the University of Oxford have combined DNA origami and DNA motors to take another step toward programmed artificial molecular assembly lines.

Crowd-sourced protein design a promising path to advanced nanotechnology

Foldit game players have again out-performed scientists in protein design, this time improving the design of a protein designed from scratch to catalyze Diels-Alder cycloadditions.

Advanced nanofactories in twenty years?

An article in The Guardian quotes Christine Peterson and Robert Freitas on the vision of molecular manufacturing. Freitas is quoted as expecting that the development of nanofactories could be done in 20 years for “on the order of” one billion dollars.

First Master's of Science in Nanomedicine degree program in US announced

The first Master’s of Science in Nanomedicine degree program in US is announced. As an example of the rapidly developing potential of nanomedicine, a novel type of nanoparticle succeeded in two different mouse models in destroying a type of brain cancer that had previously been completely resistant to all treatment attempts.

Arrays of artificial molecular machines could lead to atomically precise nanotechnology

A tutorial review available after free registration presents a theory-based exploration of the difficulty in moving from simple molecular switches to arrays of artificial molecular machines capable to doing substantial, useful external work.

RNA CAD tool for synthetic biology may facilitate RNA nanotechnology

RNA CAD tools developed for RNA-regulated control of gene expression in synthetic biology successfully engineered metabolic pathways in bacteria. Will engineering RNA-based genetic control systems lead to design tools for other RNA-based molecular machine systems?

Mechanical pressure produces atomically-precise, multifunctional 2D sheets

Protein-like structures called peptoids can be formed into stable, free-floating nanosheets.

Christine Peterson on current state and future potential of nanotechnology

When can we expect advanced nanomachinery to be commercialized? Will any technologies not be affected in some way by advanced nanotechnology?
