Figure 8
In vivo imaging of silver-coated hollow glass beads in a live mouse trachea. The image on the left was captured approximately 2 min after imaging was started. The strips on the right are motion-detected frames 42 s apart from within the marked white rectangle. The motion of four separate particles is marked: two are moving up the trachea at different speeds, and two are moving more slowly down the trachea. A large number of smaller particles moved faster than these, but are not clear on these static images. The majority of the glass bead particle transit was located toward the dorsal tracheal wall. Movie S4 in the online supporting information (GlassBeads.avi) contains a time-lapse movie of the in vivo behaviour of hollow glass beads.
