      abstract     = {Mutual uncrossability of polymers generates topological
                      constraints on their conformations and dynamics, which are
                      generally described using the tube model. We imaged
                      confinement tubes for individual polymers within a F-actin
                      solution by sampling over many successive micrographs of
                      fluorescently labeled probe filaments. The resulting average
                      tube width shows the predicted scaling behavior.
                      Unexpectedly, we found an exponential distribution of tube
                      curvatures which is attributed to transient entropic
                      trapping in network void spaces. Copyright (C) EPLA, 2009},
