The run_intertial_mass_determination() method generates automatically figures of the curve fitting for the per pre experiment data with and without a cell attached to the cantilever. A combined figure illustrating the shift in the phase response and the function fits and the resulting calculated cell mass of the long term measurement data.

Show resulting plots

  • Shift in the phase response with and without cell attached to the cantilever and the corresponding function fit Phase response shift
  • Final result of the mass calculation for the long term data set Calculated cell mass
