Abstract

original image

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.
