Tiny tool to control growing blood vessels opens new potential in tumor research February 21, 2009 Researchers at Uppsala University have developed a new tool that makes it possible to study the signals in the body that control the generation of blood vessels. The researchers' findings, published in the new issue of Lab on a Chip, enable scientists to determine what signals in the body attract or repel blood vessels, knowledge that is extremely interesting in tumor research. |

The gold standard: Biodesign Institute researchers use nanoparticles to make 3-D DNA nanotubes January 01, 2009 Researchers at ASU's Biodesign Institute and faculty in the Department of Chemistry and Biochemistry, reveal for the first time the 3-D character of DNA nanotubules, rings and spirals, each a few hundred thousandths the diameter of a human hair. These DNA nanotubes and other synthetic nanostructures may soon find their way into a new generation of ultra-tiny electronic and biomedical innovations. |
