Figure 2 Close Encounters of the Virtual Kind Return to article Figure 2. Mike Falvo of the University of North Carolina uses the nanomanipulator to maneuver a colloidal particle into a gap that had been etched in a thin, gold wire. The area under study is about 1 micron on a side. The colloidal gold particle is about 15 nm across. The vertical scale has been exaggerated by a factor of five over the horizontal to bring out surface features.
Yellow lines mark the progress of the tip during modification.
