Nanotechnology researchers in London have used a scanning tunneling microscope to create atomically precise quantum states from dangling bonds on a silicon surface.

RNA-protein motor for unidirectional movement of DNA in nanomachinery

Posted by Jim Lewis on April 1st, 2013

Revolution of DNA around a central channel, rather than rotation, is the method used by a viral molecular motor to package DNA. A structure facilitating bottom-up assembly may lead to roles in nanotechnology for these nanomotors.

Nanotechnology revolution: An interview with Eric Drexler

Posted by Stephanie C on March 29th, 2013

In anticipation of Eric Drexler’s new book, Forbes contributor Bruce Dorminey interviews him about the meaning of nanotechnology and its revolutionary prospects. Selected excerpt: … In what fields would APM cause the most pronounced economic disruption and the collapse of global supply chains to more local chains? The digital revolution had far-reaching effects on information [...]

Re-engineering a junction to give a new twist to DNA nanotechnology
