PHYS brown bag seminar: Response of model tissues to frequency-dependent aspiration

Presenter: Grégory Beaune (Active Matter group)

Abstract:

We have developed an improved version of the pipette aspiration technique to probe the mechanical properties of viscoelastic materials. One of the unique abilities of this technique is to apply frequency-dependent pressures. Here we investigate the response of cellular aggregates, used as model tissues, to such controlled external stresses. We study the impact of the applied pressure and the frequency of the pressure. We also explore a mechanosensitive cell response of aggregates called shivering.
