Study of particle-substrate interaction by nanomanipulation experiments with dynamic scanning force microscopy — •Claudia Ritter1, Markus Heyde2, and Klaus Rademann1 — 1Humboldt-Universität zu Berlin, Institute of Chemistry, Brook-Taylor-Str. 2, D-12489 Berlin, Germany — 2Fritz-Haber-Institute of the Max-Planck-Society, Faradayweg 4-6, D-14195 Berlin, Germany
We utilise an advanced homebuilt SFM in the dynamic mode, in conjunction with a special homebuilt software, to perform precise nanomanipulation experiments. The corresponding experimental technique should be denoted as Dynamic Surface Modification (DSM), comprising both the dynamic technique of the SFM, as well as the manipulation (translation, in-plane rotation, cutting) of structurally unchanged particles on a given substrate surface. It is easily possible to switch between imaging mode and DSM mode, enabling the direct manipulation of nanoparticles under ambient conditions with high precision and simultaneously studying particle-substrate interaction to give evidence about motion and tribological values of the sample system. We have successfully manipulated miscellaneous nanoparticles on surfaces, e.g. antimony islands, gold islands, tin islands, nanotubes, small latex spheres as well as cells.
