In the previous research held by Departments of Biological Chemistry and Molecular Pharmacology and Genetics, Harvard Medical School, Boston, and Department of Cancer Biology, Dana–Farber Cancer Institute, Boston, the induced alignment of membrane proteins has been used for NMR structure determination.
Yet recently, Arizona State University researchers reveal for the first time the three-dimensional character of DNA nanotubules, rings and spirals, each a few hundred thousandths the diameter of a human hair.
One of the researchers, Yan said, he has been much inspired by nanoscale ingenuity in the natural world. This was the reason why they based the research on the DNA molecule’s remarkable properties of self-assembly. They use a 10-nm-size gold nanoparticles, where the DNA nanotubes form a split branch structure, with both the spiral tube splitting into two smaller stacked rings.
ScienceDaily reported that these DNA nanotubes and other synthetic nanostructures may soon find their way into a new generation of ultra-tiny electronic and biomedical innovations. Source and Credit : ScienceDaily
