the gold reduces hydrogen peroxide into water, in doing so an electron is pulled from the gold. This causes a steady electron flow from the platinum side of the rod towards the gold side. Since the rod is so small, Newton's third law of physics applies. For any action there is a reaction, when the electrons are pulled across the surface of the rod, so too is the rod pulled in the opposite direction. Scientific achievements The first recorded success of a nanosubmarine was performed by a team of students led by Dan Peer from Tel Aviv University in Israel. This was a continuation to Peer's work at Harvard on nanosubmarines and targeted drug delivery. Tests have proven successful in delivering drugs to heal mice with ulcerative colitis. Tests will continue and the team plans to experiment on the human body soon. See also Fantastic Voyage, novel and movie based on the nanosubmarine theme References Nanotechnology
