Low Interaction Force Imaging with NANOSENSORS™ Heartbeat Cantilevers

ScnAsstLmll_fig12

A thin and very flexible polymer lamella with a high aspect ratio should be characterized by Atomic Force Microscopy. When imaged in Tapping Mode, we can see that the position of the lamella in trace- and retrace-images is shifted (figures 3 and 4). The lamella is dragged by the tip towards the scan direction and slips away (see figure 7). Of course, those images do not represent the true structure of the surface. To avoid this “drag-and-slip” effect the lamella was imaged with a NANOSENSORS™ Heartbeat Cantilever in a low force interaction mode (ScanAsyst®, figures 5 and 6). When overlaying cross-sections from trace and retrace of the images it becomes clear that the NANOSENSORS™ Heartbeat Cantilever images are superimposable and depict the sample precisely (figure 8).ScnAsstLmll_fig34
