The Nanowalker: DNA Robot Takes Its First Steps

A microscopic biped with legs just 10 nanometres long and fashioned from fragments of DNA has taken its first steps. The nanowalker is being hailed as a major breakthrough by nanotechnologists. The biped’s inventors, chemists Nadrian Seeman and William Sherman of New York University, say that while many scientists have been trying to build nanoscale devices capable of bipedal motion, theirs is the first to succeed — via GeneWeb
