(a) Force as a function of structural stiffness; (b) force as a function of cell spread area; (c) failure occurrence locations for OI-Single mode (probe side, no probe side, and both sides) and OI-Dual mode (left probe side, right probe side, and both sides); and (d) the angle created between the actuated and passive fiber (probe angle) shows that the single probe angle is larger than dual probe angle for each diameter (scale bar, 25 μm; n = 188).
