Nano-scale DNA research tool created

Researchers have made a very small research tool that may one day help scientists probe the activity of genes and proteins in a single cell, opening the door to a new realm of genetic research. "We have made little chips that are like the gene chips but instead of being lab scale they are molecular scale," says Stuart Lindsay, physics professor. "They have the potential to be used all the way down into analyzing single cells," he says.Article source: Scientific American
