Using over 100,000 CPU hours, a Zyvex/IMM/Georgia Tech team including the familiar-to-Nanodot names of Robert Freitas, Ralph Merkle, Jim Von Ehr, and John Randall — along with soon-to-be-familiar co-authors Jingping Peng and George Skidmore — have modeled the mechanosynthesis of diamond onto a 200-atom surface. Published in the Journal of Computational and Theoretical Nanoscience (1… Continue reading Diamond mechanosynthesis modeled on 200-atom surface
A UK/France/Italy/Netherlands/Czech team have announced the building of a new nanosensor/switch/actuator. As described by CORDIS (Source: Foresight News Digest): “The motor is attached to the [DNA] strand at the specific sequence of bases. Then the team introduces ATP, the phosphate molecule that provides energy within living cells, into the microfluidics channel. This is the fuel… Continue reading European team make nanoactuator
Over at the Nanotech Briefs’ Nano Test Blog is a post on work by UIUC physicist Paul Selvin showing that myosin VI can act as a molecular transporter: ” ‘We found that, at high enough concentrations, some of the myosin molecules would find one another, they would dimerize, and they would start walking,’ Selvin said…’And,… Continue reading Myosin can act as molecular transporter
The IEEE Virtual Museum, targeted at the general public, has opened its nanotech exhibit. An excerpt: “Even with these real-world applications, the current uses of nanotechnology (other than nano-size particles of various materials) remain very limited…However, researchers are rapidly making progress toward what some think of as true nanotechnologies—self-assembling, molecule size machines to perform all… Continue reading Nanotech exhibit opens at IEEE Virtual Museum
From Livescience: “In another feat in the effort to truly downsize Detroit, the researchers have now installed a miniature, light-powered motor in their diminutive automobile. “The nanocar is about as wide as a strand of DNA. Roughly 20,000 of them could park side-by-side in a lot no wider than a human hair. “Such small devices… Continue reading Nanocar gets nanomotor via US/Dutch collaboration
Now available over at e-drexler.com, a new article from the Journal of Computational and Theoretical Nanoscience, Toward Integrated Nanosystems: Fundamental Issues in Design and Modeling (2.2 MB PDF), by Foresight founder K. Eric Drexler of Nanorex, Inc. Though it sounds intimidating, the article is actually quite accessible and should serve as a good introduction to… Continue reading Fundamental issues in integrated nanosystems: Now made accessible
Now in its sixth revision, the lastest version of the Foresight Guidelines for Responsible Nanotechnology Development was released today (HTML or 116 KB PDF), just in time for a presentation this morning by Foresight Research Associate Dr. David Forrest to the U.S. Senate Committee on Environment and Public Works’ meeting for nanotechnology stakeholders. Excerpt: “Version… Continue reading Foresight nanotech R&D guidelines: new version released
In their Medical Products industry section, Accenture analysts Roland Hengerer and Martin Illsley describe what we can expect from nanotech for medicine: “To give just a sense of the possibilities, scientists and engineers are experimenting with ways to ‘nanostructure’ matter in such a way as to create industrial materials that are 100 times stronger than… Continue reading Accenture on nanotech for medicine
From New Scientist, news of an achievement at University of Tokyo: “the first combination of two molecular machines is an important step on the long path to nanodevices sophisticated enough to, for example, perform repair functions within our cells. ” ‘The next step is to integrate multiple molecular machines’ into much bigger devices, says Kazushi… Continue reading First molecular machine combination made in Japan
Earth & Sky brings us comments on nanosurveillance: “Nanotechnology experts have suggested that nano sensors — tiny devices too small to see with the unaided eye and able to monitor sounds and physical conditions — could be put into paint and sprayed on a wall. “David Guston [Director of the Center for Nanotechnology in Society… Continue reading Nanosurveillance comments from Arizona State, Bell Labs
