Abstract

Dynamic force microscopy (DFM) in combination with special-purpose probe control software is used as a manipulation tool for the precise positioning of single gold nanoparticles on a mica substrate covered with a poly-L-lysine film. Experimental results are presented that show how to construct arbitrary patterns of nanoparticles. The dynamic state of the cantilever during the manipulation process is studied experimentally by analyzing the simultaneously recorded non-contact amplitude and cantilever deflection. Numerical simulations guide and supplement the experiments in order to provide a physical description of the manipulation mechanism. The results presented here show that the nanoparticles are pushed along the surface once a critical contact force between tip and gold cluster is exceeded. In addition, a method for estimating the average separation between the tip apex and the sample in DFM is described.
