TABLE 1:
Summary of orientation during motility initiation and switching for uncoated beads.
| Motility initiation | ||||||||
|---|---|---|---|---|---|---|---|---|
| Start migrating parallel | 1 switch | 2 switches | Start migrating perpendicular | 1 switch | 2 switches | Parallel-to-perpendicular switching events | Perpendicular-to-parallel switching events | |
| Spontaneous (n = 15 beads) | 15 | 5 | 1 | 0 | 0 | 0 | 6 | 1 |
| Collision-induced (n = 20 beads) | 17 | 0 | 0 | 3 | 0 | 0 | 0 | 0 |
| Total (n = 35 beads) | 32 | 5 | 1 | 3 | 0 | 0 | 6 | 1 |
| Steady-state motility | ||||||||
| Beads | 1 switch | 2 switches | Events | Parallel to perpendicular | Perpendicular to parallel | |||
