Figure 4.
Movement of dense network regions in the coarse network. (A) Mobility maps of immobile (red) and mobile (yellow) probes in a 1% κ-carrageenan, 200 mM NaCl, and 20 mM KCl gel. The position of all particles found in the time range 1–20 s (left) or 21–40 s (right) are overlaid. The white-dotted outline represents the proposed outline of the dense region (B) RCM images show a migrating dense network region (indicated by arrows) in a 1% κ-carrageenan, 200 mM NaCl, and 20 mM KCl gel (also see Movie S.1). Images represent single RCMs, except for the 6–73 and 79–156 s images, where the median of the corresponding RCMs is shown.
