A response to my “Parricide” essay has been seen on IEEE’s Tech Talk blog. Dexter Johnson gives a fair summary of the positions taken to date, and says As the argument seems to go, Drexler popularized the term nanotechnology in his book Engines of Creation, and so when the general public heard that thousands of… Continue reading The nanotechnology we were promised
New computational results reveal how the proper hierarchical assembly of smaller protein domains optimizes mechanical properties.
A new nanocar that runs cool — at room temperature — has been demonstrated by the research group of Stephan Link, colleague of James Tour at Rice. Tour won Foresight’s Feynman Prize last year for his earlier nanocar work. This press release describes several novel features of the latest work. In particular, the new cars… Continue reading Cool new nanocars
Computer simulations have shown that graphene deposited on a silicon dioxide surface will be either a semiconductor or a metal depending on whether the underlying layer is terminated with oxygen atoms or passivated with hydrogen atoms.
Canadian scientists have discovered how chemical structure can elicit a quantum state that permits the ultrafast movement of energy along an organic polymer.
The synthesis and characterization of molecules called cycloparaphenylenes could provide nanotech with an efficient way of producing armchair carbon nanotubes of pre-determined diameter.
DNA nanotech continues to improve the devices it produces as Oxford University scientists fix several shortcomings seen in earlier versions of bipedal DNA molecular walkers.
Researchers have been able to attach gold nanoparticles to DNA tiles and, by varying the size of the nanoparticles and the presence of DNA stem loops on some tiles, have been able to control the formation from the DNA tiles of various three dimensional DNA nanotubes.
Scientists have now revealed the working mechanism of one of the most powerful molecular motors known to biology.
A new nanotech method of DNA sequencing is 30,000 times faster than current DNA sequencing methods.
