    Abstract: An analytical solution of the vibration responses of biological specimens using atomic force microscopy
    (AFM), which often requires operation in a liquid, is developed. In this study, the modal superposition
    method is employed to analyze the vibration responses of AFM cantilevers in tapping mode (TM)
    operated in a liquid and in air. The hydrodynamic force exerted by the fluid on AFM cantilevers is
    approximated by additional mass and hydrodynamic damping. The tip–sample interaction forces were
    transformed into axial, distributed transversal, and bending loading, and then applied to the end region
    of the AFM through the tip holder. The effects of transverse stress and bending stress were adopted to
    solve the dynamic model. With this model, a number of simulations were carried out to investigate the
    relationship between the transient responses of the cantilever in a liquid and the parameters considered
    in nanoscale processing. The simulations show that the vibration of AFM cantilevers in a liquid has
    dramatically different dynamic characteristics from these of that in air. The liquid reduces the magnitude
    of the transversal response and reduces the cantilever resonances. Moreover, the magnitudes of response
    become larger with increasing intermolecular distances and smaller with decreasing tip length. The
    cantilever vibration amplitudes significantly depend on the damping constant and the mass
    proportionality constant.
