Claim 8:
9. A method for determining a mechanical property of a viscoelastic sample with an atomic-force-microscope (AFM) hardware, the method comprising:
with the use of the apparatus according to claim 1:
monitoring, with electronic circuitry of the apparatus, an operation of the apparatus at a reference frequency to correct for a change in at least one of (i) an area of contact between a tip of a cantilevered probe of the AFM hardware of the apparatus and a surface of the viscoelastic sample and (ii) an average sample-loading force, generated by said cantilevered probe and
measuring, at a set of frequencies that cover at least one decade in a frequency space, a viscoelastic parameter of a surface of the viscoelastic sample.
