AFM artifacts: Recent results by Sajanlal and Pradeep on the electric‐field‐assisted growth of highly uniform and oriented gold nanotriangles appear to provide a simple route to the size‐, shape‐, and orientation‐controlled synthesis of nano structures. In our view, however, the triangle patterns observed in the AFM images are not real surface features but artifacts produced by a broken or contaminated AFM tip.
