This Article contains an error in the order of the Figures. Figures 5 and 6 were published as Figures 6 and 5 respectively. The correct Figures 5 and 6 appear below as Figures 1 and 2. The Figure legends are correct.
Figure 1.
(A) The obtained InvOLS values measured in 1 μm steps on the polystyrene substrate with the three FluidFM cantilevers. The curves represent a 5th grade polynomial fit on the datasets. (B) The spring constant measured in 1 μm steps in air with the three FluidFM cantilevers, as functions of the laser spot position.
Figure 2.
(A) The noise levels calculated as mean squared error (MSE) of linear fit on the baseline of a forcecurve (see Fig. 1B). (B) The same MSEs, measured on the linear indentation (approach) section of the forcecurve, which was used for InvOLS calculations.
