Figure 7

Trajectory of trapped cell as a function of image sequence. (A) Horizontal and (B) vertical coordinates are represented with respect to the trap center located at the origin. (C) Thick arrows indicate the moving direction of the cell whose position converged to the focus. (D) The increment of the vertical displacement is found until frame #8 and then decreased afterwards. This illustrates a spring-like pattern when it is released after being stretched beyond the equilibrium point (reviewer #2).
