New efficiency benchmark for dye-sensitized solar cells
In a paper published online June 29 in the journal Nature Materials, EPFL professor Michael Graetzel, Shaik Zakeeruddin and colleagues from the Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences have achieved a record light conversion efficiency of 8.2% in solvent-free dye-sensitized solar cells.

Brown Chemists Create Cancer-Detecting Nanoparticles
A team led by a Brown University chemist has created the smallest iron oxide nanoparticles to date for cancer detection by magnetic resonance imaging (MRI). The magnetic nanoparticles operate like tiny guided missiles, seeking and attaching themselves to malignant tumor cells. Once they bind, the particles emit stronger signals that MRI scans can detect.

Failed HIV Drug Gets Second Chance with Addition of Gold Nanoparticles
Researchers at North Carolina State University have discovered that adding tiny bits of gold to a failed HIV drug rekindle the drug's ability to stop the virus from invading the body's immune system. (2008-05-27)

By Adding Graphene, Researchers Create Superior Polymer
Researchers at Northwestern University and Princeton University have created a new kind of polymer that, because of its extraordinary thermal and mechanical properties, could be used in everything from airplanes to solar cells. (2008-05-20)

As nanotech goes mainstream, 'toxic socks' raise concerns
Nanotechnology is now available in a store near you. Valued for it's antibacterial and odor-fighting properties, nanoparticle silver is becoming the star attraction in a range of products from socks to bandages to washing machines. But as silver's benefits propel it to the forefront of consumer nanomaterials, scientists are recommending a closer examination of the unforeseen environmental and health consequences of nanosilver.

Nano-sized technology has super-sized effect on tumors
Anyone facing chemotherapy would welcome an advance promising to dramatically reduce their dose of these often harsh drugs. Using nanotechnology, researchers at Washington University School of Medicine in St. Louis have taken a step closer to that goal. (2008-04-03)

Think green, UO's Hutchison says, to reduce nanotech hazards
The University of Oregon's Jim Hutchison already holds three patents in the emerging field of nanotechnology as well as leadership roles in organizations that promote the technology's potential in materials science and medicine. (2008-04-01)

Inhaled tuberculosis vaccine more effective than traditional shot
A novel aerosol version of the most common tuberculosis (TB) vaccine, administered directly to the lungs as an oral mist, offers significantly better protection against the disease in experimental animals than a comparable dose of the traditional injected vaccine, researchers report this week in the Proceedings of the National Academy of Sciences. (2008-03-13)

All done with mirrors: NIST microscope tracks nanoparticles in 3-D
A clever new microscope design allows nanotechnology researchers at the National Institute of Standards and Technology (NIST) to track the motions of nanoparticles in solution as they dart around in three dimensions. (2008-03-11)

Researchers identify and shut down protein that fuels ovarian cancer
A protein that stimulates blood vessel growth worsens ovarian cancer, but its production can be stifled by a tiny bit of RNA wrapped in a fatty nanoparticle, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the Journal of the National Cancer Institute. (2008-02-27)
