invasiveness of the measurement. The parametricalequation obtained by Raman et al. has been based on the Hertzian mechanics for air and vacuum environments [21]. It has been also adapted to estimate the experimental peak forces of viral capsids (ca. 1 GPa) in liquid [22]. However, those parametrical

Here, a parametricalequation to determine the peak interaction force exerted by the AM-AFM on a finite soft material immersed in a liquid environment
