Nanotechnology Innovation May Revolutionize Gene Detection In A Single Cell
Scientists at Arizona State University’s Biodesign Institute have developed the world’s first gene detection platform made up entirely from self-assembled DNA nanostructures. The results, appearing in the January 11 issue of the journal Science, could have broad implications for gene chip technology and may also revolutionize the way in which gene expression is analyzed in a single cell.
“We are starting with the most well-known structure in biology, DNA, and applying it as a nano-scale building material, ” said Hao Yan, a member of the institute’s Center for Single Molecule Biophysics and an assistant professor of chemistry and biochemistry in the College of Liberal and Sciences.
Yan is a researcher in the fast-moving field known as structural DNA nanotechnology — that assembles the molecule of life into a variety of nanostructures with a broad range of applications from human health to nanoelectronics.
