Figure 2.

Dependence of vault stability on force imaging. (A) Sequential topographic images taken at ∼3 min intervals, each frame labeled with its corresponding imaging force. Scale bar, 50 nm. A comparison of the profiles (frame 7, inset) taken along the dotted lines of the topographies in frames 1 (dotted black line) and 7 (dotted green line) shows partial collapse of the structure. (B) Imaging force evolution (upper) and maximal height evolution of the half-vault (black) and the reclining particle (red). To see this figure in color, go online.
