Scientists create 99 percent pure nanorods

HOUSTON, Sept. 24 (UPI) -- U.S. chemists say they've discovered a technology that permits them to produce ultra-pure gold nanorods that are about 99 percent pure. "The content of high-aspect-ratio gold nanorods produced by today's best synthetic methods is only about 20 percent," said Rice University Assistant Professor Eugene Zubarev, who is leading the research.
