Berkeley Researchers Find New Route to Nano Self-Assembly
If the promise of nanotechnology is to be fulfilled, nanoparticles will have to be able to make something of themselves. An important advance towards this goal has been achieved by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) who have found a simple and yet powerfully robust way to induce nanoparticles to assemble themselves into complex arrays. (2009-10-23)
Growing geodesic carbon nanodomes
Researchers analyzing the assembly of graphene (sheets of carbon only one atom thick) on a surface of iridium have found that the sheets grow by first forming tiny carbon domes. (2009-10-12)
A recipe for controlling carbon nanotubes
Nanoscopic tubes made of a lattice of carbon just a single atom deep hold promise for delivering medicines directly to a tumor, sensors so keen they detect the arrival or departure of a single electron, a replacement for costly platinum in fuel cells or as energy‐saving transistors and wires. (2009-09-21)
Molecules on a string, and why size isn't the only thing that matters for data storage
Molecules of hydrogen are difficult to steer with electric fields because of the symmetrical way that charges are distributed within them. But now researchers at ETH Zurich have found a clever technique to get a grip on the molecules. (2009-09-15)
An HIV-blocking gel for women
University of Utah scientists developed a new kind of "molecular condom" to protect women from AIDS in Africa and other impoverished areas. Before sex, women would insert a vaginal gel that turns semisolid in the presence of semen, trapping AIDS virus particles in a microscopic mesh so they can't infect vaginal cells. (2009-08-10)
Purer water made possible by Sandia advance
By substituting a single atom in a molecule widely used to purify water, researchers at Sandia National Laboratories have created a far more effective decontaminant with a shelf life superior to products currently on the market. (2009-07-22)
Optical techniques show continued promise in detecting pancreatic cancer
Optical technology developed by a Northwestern University professor of biomedical engineering has been shown to be effective in detecting the presence of pancreatic cancer through analysis of neighboring tissue in the duodenum, according to clinical trial results published in the journal Disease Markers. (2009-03-03)
Nanoscopic changes to pancreatic cells reveal cancer
A team of researchers in Chicago has developed a way to examine cell biopsies and detect never-before-seen signs of early-stage pancreatic cancer, according to a new paper in the Optical Society (OSA) journal Optics Letters. (2009-02-13)
A crystal clear view of chalk formation
Chalk crystallizes differently from the way we once thought it did. This discovery will allow the development of new scale inhibitors and other materials, and has also consequences for climate change. (2009-01-26)
Tension in the nanoworld
A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors. (2009-01-26)
