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 …

A bottom-up approach to cell mechanics

AR Bausch, K Kroy - Nature physics, 2006 - nature.com
The mechanical stability and integrity of biological cells is provided by the cytoskeleton, a
semidilute meshwork of biopolymers. Recent research has underscored its role as a …

Stochastic mechano-chemical kinetics of molecular motors: a multidisciplinary enterprise from a physicist's perspective

D Chowdhury - Physics Reports, 2013 - Elsevier
A molecular motor is made of either a single macromolecule or a macromolecular complex.
Just like their macroscopic counterparts, molecular motors “transduce” input energy into …

Helical twist controls the thickness of F-actin bundles

MMAE Claessens, C Semmrich… - Proceedings of the …, 2008 - National Acad Sciences
In the presence of condensing agents such as nonadsorbing polymer, multivalent counter
ions, and specific bundling proteins, chiral biopolymers typically form bundles with a finite …

Kinetochore-and chromosome-driven transition of microtubules into bundles promotes spindle assembly

J Matković, S Ghosh, M Ćosić, S Eibes… - Nature …, 2022 - nature.com
Mitotic spindle assembly is crucial for chromosome segregation and relies on bundles of
microtubules that extend from the poles and overlap in the middle. However, how these …

Triggered contraction of self-assembled micron-scale DNA nanotube rings

M Illig, K Jahnke, LP Weise, M Scheffold… - Nature …, 2024 - nature.com
Contractile rings are formed from cytoskeletal filaments during cell division. Ring formation is
induced by specific crosslinkers, while contraction is typically associated with motor protein …

Semiflexible biopolymers in bundled arrangements

J Schnauß, T Händler, JA Käs - Polymers, 2016 - mdpi.com
Bundles and networks of semiflexible biopolymers are key elements in cells, lending them
mechanical integrity while also enabling dynamic functions. Networks have been the subject …

Dilute semiflexible polymers with attraction: Collapse, folding and aggregation

J Zierenberg, M Marenz, W Janke - Polymers, 2016 - mdpi.com
We review the current state on the thermodynamic behavior and structural phases of self-
