  We assume that the sample height measured using AFM is reduced due to contact
deformation. The Herz contact theory is applied for the quantitative
description. General numerical solution is found. Analytical approximations for
specific contact geometry are derived for the case of cylindrical sample. It is
found that theoretical description are consistent with experimental data. The
developed approach has allowed to determine elastic parameters of individual
microobjects adsorbed on a surface of solid substrate.
