| Method |
"[Researchers] image the swimming trajectories of singly flagellated
Caulobacter crescentus near a surface with dark-field
and total internal reflection fluorescence (TIRF) microscopy. TIRF, in particular, restricts the imaging of the labeled cell body within a few hundred nanometers away from the surface with the image intensity sensitively dependent on the distance, thus resolving reliably the effect of distance on the swimming behavior." |
| Comments |
"The closer the bacterium is to the surface, the larger the drag. Therefore, it swims slower when closer to the surface. The results shown in Fig. 3B support this prediction, although the data are also highly scattered." Range extracted visually from fig.3B |
