    • note
    • The lower magnitude of friction forces at constant load observed in ref 49 for higher pH should be predominantly attributed to a decrease in the effective (actual) normal load, because of a buildup of the repulsive double-layer force. Some change in a friction coefficient, however, can also be detected in friction force versus normal force curves presented in that work.

    • 13d We attribute it to strong height -friction coupling unavoidable in AFM experiments if the tip is scanned parallel to the cantilever axis of symmetry (see: Radmacher, M.; Tillman, R. W.; Fritz, M.; Gaub, H. E. Science 1992, 257, 1900. Warmack, R. J.; Zheng, X.-Y.; Thundat, T.; Allison, D. P. Rev. Sci. Instrum. 1993, 65, 394). In our experiment the tip was scanned in the perpendicular direction which eliminated the coupling.

    • note
    • 4 tips are used for imaging of patterned surfaces in fluids, the image contrast is very often unpredictable and even changes during scanning.
