Physorg.com and many others report a molecular nanotechnology achievement by a UCLA/Caltech nanotech team: A team of UCLA and California Institute of Technology chemists reports in the Jan. 25 issue of the journal Nature the successful demonstration of a large-scale, “ultra-dense” memory device that stores information using reconfigurable molecular switches. This research represents an important… Continue reading Ultra-dense memory device uses molecular nanotechnology
Alert reader Ron Zilm brings our attention to a nanotechnology research achievement at UC Riverside in California by Ludwig Bartels, originally a physicist in Germany but now in the UCR chemistry department: Walking Molecule Now Carries Packages Molecule walks in a straight line and carries a tiny shopping bag in each hand A research team,… Continue reading Nanotechnology movie: Walking molecule now carries packages
In addition to the experimental project described here yesterday, there are now two more posted on the U.K. Software Control of Matter Ideas Factory blog which are very likely to be funded — the first experimental, the second theoretical: Directed Reconfigurable Nanomachines We propose a scheme to revolutionise the synthesis of nanodevices, nanomachines, and, ultimately,… Continue reading U.K. nanotechnology project causing U.S. nanoenvy
Christian Joachim, winner of Feynman Prizes in Nanotechnology for both experiment and theory, continues his exciting molecular machine systems work with a recent publication authored by a German/French team in Nature Materials titled “A rack-and-pinion device at the molecular scale“. From the summary and conclusion: In this work, we present a molecular rack-and-pinion device for… Continue reading European nanotechnology team builds molecular rack-and-pinion
We’ve written before about the nanotechnology-based matter compiler project in the U.K, wishing we could participate. Richard Jones writes that now, we can: You may be interested to hear (and I’m hoping you might post about it on your blog) that we’ve now got a blog running associated with the “Software Control of Matter” sandpit.… Continue reading Now we all can assist UK nanotechnology project
Allison Stoddart of the Royal Society of Chemistry’s magazine Chemical Science interviews nanotechnology researcher David Leigh on the joy of molecular machines in a piece titled “The magic of chemistry”: What motivated you to study molecular machines? I worked in Fraser Stoddart’s group before he made any catenanes or rotaxanes. We made our first catenane… Continue reading Molecular machines: the magic of nanotechnology
In yet another promising example of nanotechnology being used to defeat cancer, Forbes.com tells us of work at University of Michigan on brain cancer research: Tiny “nanoparticles” can be loaded with high concentrations of drugs to kill brain cancer, U.S. researchers report. Researchers at the University of Michigan (U-M) Comprehensive Cancer Center incorporated the drug… Continue reading Nanotechnology to fight brain cancer
The useful website Nanowerk describes a new technique invented by researchers in Spain which should be useful in analyzing nanotechnology devices: Many protein molecules, such as those that process DNA, execute twisting motions, but researchers have only managed to measure the torques in a few cases. Often the random thermal jiggling of water molecules makes… Continue reading Nanotechnology torque detected with exquisite sensitivity
NYU prof Nadrian Seeman, who won the Foresight Institute Feynman Prize back in 1995, has done it again. From Science Daily: New York University chemistry professor Nadrian C. Seeman and his graduate student Baoquan Ding have developed a DNA cassette through which a nanomechanical device can be inserted and function within a DNA array, allowing… Continue reading Nanotechnology robotic arm built at NYU
The Future of Things, an online magazine based in Israel, has a nanotechnology article/interview with the clearest explanation I’ve seen of the two generations of nanocars built at Rice University. We’ve discussed this before, but a more comprehensible exposition is always welcome. See especially the Flash movie of how the latest nanocar moves. Some excerpts:… Continue reading New nanotechnology movie shows nanocar propulsion
