Abstract:
The era of nano-manufacturing is being born in hundreds of labs that are racing to perfect a technique called self-assembly. If you just listen casually to a description of what Sandia National Laboratories has been working on, you would think it had wasted its time reinventing the wheel: It has developed a robot that can walk and pick up and deliver loads of cargo. In an age of advanced assembly and landings on Mars, that hardly sounds impressive -- except that Sandia's robot is a molecule.
