Mobility mapping of immobile and mobile regions in κ-carrageenan gels. (A) Procedure to sort single localizations in immobile (red), mobile (yellow), or intermediate (discarded) groups based on the mjd of their corresponding track. (B) Representative image of a resulting pseudo-color-coded mobility maps. Red regions are locations consisting of solely immobile particles, yellow regions are locations consisting of solely mobile particles, and orange regions (arrows) are locations where both immobile and mobile probes are present. The outlined region is enlarged in (C). (C) Zoom-in from (B) with a proposed schematic network structure overlaid on the image. Dense network regions show translational migration in κ-carrageenan hydrogels.
