Scanning probes were used to manipulate the individual molecule beads on the molecular abacus in Figure 1.3. They have also been used to make wonderful nanoscale graffiti by arranging atoms or molecules on surfaces with particular structures. These structures have been used to demonstrate and test some fundamental scientific concepts ranging through structural chemistry, electrical ...
