Molecular dynamics simulations of active entangled polymers reptating through a passive mesh

Conformation and dynamics of partially active linear polymers

“…From a more polymeric perspective, it would be interesting to investigate how the position of a block of active monomers influences the entanglement in very dense conditions. 61,62 Finally, as mentioned in the introduction, chromatin is distinctly characterized by ''sections'', among which the active one is bound to be out-ofequilibrium due to the action of ATP-driven molecular motors: understanding the phenomenology of polymer chains with active sections will be important, in order to include the nonequilibrium effects in chromatin models.…”

Worm blobs as entangled living polymers: from topological active matter to flexible soft robot collectives

“…19,45–47 This theory suggests that a polymer chain in the melt exhibits “snake-like” motion within a virtual tube formed by surrounding chains, restricting its free movement, much like snakes slithering among one another. Recently, a few groups have been investigating the effect of internal activity on the reptation of polymers, either directly, 48,49 or by studying simulations of active polymers in porous environments. 50,51…”

Structure and dynamics of an active polymer chain inside a nanochannel grafted with polymers

“…[44][45][46] However, not many studies exist on the dynamics and conformations of an active polymer in a crowded medium. 25,[47][48][49] In some recent studies, it was found that active agents migrate through the crowded environment by changing their shape. [50][51][52] Bhattacharjee et al observed the hopping-and-trapping motion of bacteria in a porous medium.…”
