Researchers find gold nanoparticles capable of 'unzipping' DNA

New research from North Carolina State University finds that gold nanoparticles with a slight positive charge work collectively to unravel DNA's double helix. This finding has ramifications for gene therapy research and the ...

New treatments could reduce odors in cotton fabric

Socks, T-shirts and other garments could become less hospitable to odor-causing bacteria, thanks to new antimicrobial treatments being investigated by U.S. Department of Agriculture (USDA) scientists in New Orleans, La.

Nanostarfruits are pure gold for research

(PhysOrg.com) -- They look like fruit, and indeed the nanoscale stars of new research at Rice University have tasty implications for medical imaging and chemical sensing.

Touch of gold improves nanoparticle fuel-cell reactions

Advances in fuel-cell technology have been stymied by the inadequacy of metals studied as catalysts. The drawback to platinum, other than cost, is that it absorbs carbon monoxide in reactions involving fuel cells powered ...

Nano form of titanium dioxide can be toxic to marine organisms

The Bren School-based authors of a study published Jan. 20 in the journal PLoS ONE have observed toxicity to marine organisms resulting from exposure to a nanoparticle that had not previously been shown to be toxic under ...

New device uses gold nanoparticles to test for lung cancer

The metabolism of lung cancer patients is different than the metabolism of healthy people. And so the molecules that make up cancer patients' exhaled breath are different too. A new device pioneered at the University of Colorado ...
