The success of scanning probe microscopy (SPM) based hand-controlled single molecule manipulation technique [1,2] relies upon three main components. These are high-precision positioning of the SPM tip, a hand motion tracking system [1], and virtual reality goggles displaying the motion trajectory and feedback signals in real time [2]. With this, reproducible extraction of molecules from a closed monolayer on a metal surface and statistical determination of successful trajectories was achieved. Until now these experiments were performed on a low-temperature non-contact atomic force/scanning tunneling microscope (LT NC-AFM/STM), that has tunneling current as well as the frequency shift of the tuning fork sensor as feedback signals. Here, we study how successful trajectories can be transferred to an instrument without AFM capability (LT STM) and automatized to enable fast and efficient manipulation within monolayers.
