  The physics of adhesion of one-dimensional nano structures such as nanotubes,
nano wires, and biopolymers on different material substrates is of great
interest for the study of biological adhesion and the development of nano
electronics and nano mechanics. In this paper, we present force spectroscopy
experiments of a single wall carbon nanotube loop using our home-made
interferometric atomic force microscope. Characteristic force plateaux during
the peeling process allows us to access to quantitative values of the adhesion
energy per unit length on various substrates: graphite, mica, platinum, gold
and silicon. By combining a time-frequency analysis of the deflexion of the
cantilever, we access to the dynamic stiffness of the contact, providing more
information on the nanotube configurations and its intrinsic mechanical
properties.
