Figure 4.

(a) Sketch of mismatch diameter orientations (solid arrows represent location and direction of probe actuation), as well as data showing (b) failure occurrence, and (c) adhesion forces at failure (as measured on the passive fiber) for each case. The letter D indicates that the cell was pulled with the dual probe system, and the letter S indicates that the cell was pulled with a single probe (D8 = dual 800 nm; D4 = dual 400 nm; S8 = single 800 nm; S4 = single 400 nm; n = 51).
