Modeling semiflexible polymer networks

CP Broedersz, FC MacKintosh - Reviews of Modern Physics, 2014 - APS
This is an overview of theoretical approaches to semiflexible polymers and their networks.
Such semiflexible polymers have large bending rigidities that can compete with the entropic …

Continuum elastic models for force transmission in biopolymer gels

H Wang, X Xu - Soft Matter, 2020 - pubs.rsc.org
We review continuum elastic models for the transmission of both external forces and internal
active cellular forces in biopolymer gels, and relate them to recent experiments. Rather than …

Fluctuations, Dynamics, and the Stretch-Coil Transition of Single Actin Filaments<? format?> in Extensional Flows

V Kantsler, RE Goldstein - Physical review letters, 2012 - APS
Semiflexible polymers subject to hydrodynamic forcing play an important role in cytoskeletal
motions in the cell, particularly when filaments guide molecular motors whose motions …

Thermalized buckling of isotropically compressed thin sheets

S Shankar, DR Nelson - Physical Review E, 2021 - APS
The buckling of thin elastic sheets is a classic mechanical instability that occurs over a wide
range of scales. In the extreme limit of atomically thin membranes like graphene, thermal …

Stretching semiflexible filaments and their networks

JR Blundell, EM Terentjev - Macromolecules, 2009 - ACS Publications
Arguments are put forward that mean inextensibility is a valid approximation for semiflexible
filaments. Using mean inextensibility, a simple analytical expression for the free energy for …

Shock compression of semiflexible polymers

DA Vega, P Lance, E Zorzi, RA Register, LR Gómez - Soft matter, 2023 - pubs.rsc.org
We employ molecular dynamics simulations to investigate the shock compression of linear
semiflexible polymers. While the propagation velocity of a shock primarily depends on …

Flow-induced helical coiling of semiflexible polymers in structured microchannels

R Chelakkot, RG Winkler, G Gompper - Physical review letters, 2012 - APS
The conformations of semiflexible (bio) polymers are studied in flow-through geometrically
structured microchannels. Using mesoscale hydrodynamics simulations, we show that the …

Euler buckling and nonlinear kinking of double-stranded DNA

AP Fields, EA Meyer, AE Cohen - Nucleic acids research, 2013 - academic.oup.com
The bending stiffness of double-stranded DNA (dsDNA) at high curvatures is fundamental to
its biological activity, yet this regime has been difficult to probe experimentally, and literature …

Buckling transition of a semiflexible filament in extensional flow

H Manikantan, D Saintillan - Physical Review E, 2015 - APS
An analytical expression for the fluctuation-rounded stretch-coil transition of semiflexible
polymers in extensional flows is derived. The competition between elasticity and tension is …

Buckling of semiflexible filaments under compression

JR Blundell, EM Terentjev - Soft Matter, 2009 - pubs.rsc.org
A model for filament buckling at finite temperatures is presented. Starting from the classical
worm-like chain model under constant compression, we use a mean-field approach for …
