[Spm] baseline slope in force curves

[Olivier Arnould]

Hi,

If I have well understood, I think that this baseline slope is due to the cantilever deflection that must be substract to the z-displacement to obtain the indentation depth. This is usually done by doing a force-distance curve on a stiff material that will give you the baseline slope due to the cantilever deflection only, i.e., only a negligible indentation occurs so z-displacement ~ cantilever deflection. You have then to substract this displacement to the one you obtain on your cell.

Best regards,

Olivier Arnould
