How to Move a Single Electron

Every time you brush your hair, hundreds of trillions of electrons jump from your hair onto the brush. These particles are so small and sensitive that it is almost impossible to handle them individually, but a group of scientists from Canada have figured out a way to do it using an atomic force microscope. This newfound approach to manipulating individual electrons may one day find applications in future nanoscale electronics. An atomic force microscope can delicately reorient a silicon atom, tr...
