Fig. 1

Micropipette aspiration of polyacrylamide gels. Left part of the figure shows the two axial intensity curves (A, C) obtained along the line corresponding to the pipette axis for two video snapshots recorded during the gel aspiration (B, D). The right images (B) and (D) were taken for aspiration pressure ΔP = 0 kPa and ΔP = 16.3 kPa, respectively. The distances MN and M′N′ between the gel/glass interface and the free gel surface were precisely measured from these intensity curves, and further used to derive the aspiration length d.
