Scientists Create Diode Propulsion Engine for Bloodstream-Swimming…

Science fiction edges ever closer to reality as researchers at NC State University devise a form of propulsion that can accelerate microbots through the human bloodstream. The challenge: not only finding a way to create this engine on such a tiny scale, but to provide power to it. The solution? Diode propulsion, using… » 3/15/07 1:37pm 3/15/07 1:37pm
