Figure 1. Difference of invasiveness between trace and retrace scanning processes

Caption

(a) Raster scanning: Trace scanning (red line) and retrace scanning (blue line) of the sample stage, (b) directions of tip scanning relative to sample in trace and retrace scanning processes, (c) difference in feedback control error between the trace and retrace scanning processes. Error images of the actin filament oriented nearly along the Y-axis (top) and the error profile (bottom), (d, e) difference in the directions of torques produced by lateral and vertical forces exerted on the cantilever from the sample during trace (d) and retrace (e) scanning processes, (f, g) HS-AFM images of actin filaments captured at 10 fps in the OTI (f) and ORI (g) modes. In the ORI mode, actin filaments were quickly broken.
