In the first chapter of this thesis I discuss the importance of spatial and temporal scales in living systems, and I review the main components involved in the mechanical response of living cells. After this introductory chapter, the second one is dedicated to evaluating the mechanical response of single-cells with AFM, and in particular, its dynamical aspect. I present the analysis of force-indentation curves without any assumption on the linearity of the system, contrary to more typical analysis based on Sneddon’s or Hertz models. Then, I propose an alternative method to study the cell rheology based on the multi-frequency excitation of the cantilever by thermal noise. DPM is discussed on chapter three. I revisit the phase recovery method...
