A Schematic describing traction forces (TFs) and rigidity sensing in a cell. F, D, L and E represent TF, the diameter, length, and Young’s modulus of PDMS, respectively. ∆x; the displacement of the pillar. B Schematic and AFM (2D and 3D) topographical images of the pillar arrays. The AFM image of the pillar array was taken in ambient conditions in a contact mode. It shows that the diameter of pillars and center-to-center (c-t-c) distance between pillars are 900 nm and 1.8 μm respectively
