Researchers at IBM are developing DNA nanotechnology to assemble nanoelectronic components into arrays in a bid to replace current lithographic methods of making computer chips.
Stanford University scientists have achieved new, detailed understanding of how a polymer folds into a unique three-dimensional structure by using an “optical trap” to precisely unfold a functional RNA molecule.
Japanese scientists have succeeded in chemically attaching proteins specifically to the tips of multiwalled carbon nanotubes, avoiding contaminating attachments to the sides of the nanotubes.
French nanotech researchers have used theory to increase the precision of carving with electron beams enough to remove individual atoms from single walled carbon and boron nitride nanotubes.
Tetrahedrons made from DNA that extend and shorten in response to added short strands of DNA may provide new nanotech methods of drug delivery, but may present even more exciting possibilities for atomically precise functional nanosystems.
A new DNA base pair that works with at least one enzyme that replicates DNA opens up new possibilities for nanotech.
As we close out Nanodot for 2007, we note some predictions for the future of nanotechnology through 2025 from Peter von Stackelberg: “Between the end of the first decade of the 21st century and 2025, a number of gamechangers will need to occur if nanotech is to advance significantly,” von Stackelberg says. These gamechangers include:… Continue reading Nanotechnology: Predictions through 2025
CRN has been working on eight scenarios for advanced nanotechtechnology, and they are now available. You can get a quick feel for them by their titles: Scenario 1: Secret Military Development Scenario 2: Positive Expectations Scenario 3: Negative Drivers Scenario 4: Presidential Commission Scenario 5: … And Not a Drop to Drink Scenario 6: A… Continue reading Eight nanotechnology scenarios sketch possibilities
An article in Small Times by Paul Burrows of Pacific Northwest National Laboratory covers the Technology Roadmap for Productive Nanosystems (TRPN) aimed at Atomically-Precise Manufacturing (APM), a joint project of Foresight Nanotech Institute and Battelle, funded by the Waitt Family Foundation and by Sun Microsystems. Some excerpts: The Foresight-Battelle roadmap aimed to address this “vision… Continue reading Nanotechnology roadmap for atomically-precise manufacturing
Registration for Foresight’s Nov. 3-4 Vision Weekend focused on nanotechnology and other advanced technologies — traditionally restricted to Foresight Senior Associates — is being opened to the general public this year as an experiment. Space is limited and participants are advised to register very soon. To warm up for our Sat/Sun afternoon unconference, in the… Continue reading Nanotechnology "Unconference" now open to general public
