Quality control of the experiment: (a) average of the force-distance curves with the same speed, exhibiting a very reasonable alignment of the repulsive part of the interaction. (b) histogram of the elasticity obtained from the hertzian fit to the individual force-distance curves, grouped into series corresponding to each approach velocity, showing no dependence on approach speed; (c) histogram of the nucleation distance obtained from all the individual force-distance curves; (d) Calculated force curve using a spherical approximation (red), linear trend (brown, see text for details) and cross sectional radius (blue), the values at distances greater than 7 nm have no physical meaning. Black dots correspond to the force-distance curve performed at a tip-sample approach speed of 25 nm/s.
