Figure 21.

Schematic illustrations of (left panel) an entangled semiflexible polymer network of filaments (black lines) with an embedded tracer filament (red line). (right panel) In this case, the filaments (black lines) are either intertwined or connected by a crosslinker (blue circles). The dashed tubular structure indicates the space available to the tracer (red) filament, which is generally denoted as the reptation tube (adapted from [269]).
