Structural features and nonlinear rheology of self-assembled networks of cross-linked semiflexible polymers
Saamiya Syed, Fred C. MacKintosh, Jordan L. Shivers
Disordered networks of semiflexible filaments are common support structures in biology. Familiar examples include fibrous matrices in blood clots, bacterial biofilms, and essential…
Mechanics of fiber networks under a bulk strain
Sadjad Arzash, Abhinav Sharma, Fred C. MacKintosh
Biopolymer networks are common in biological systems from the cytoskeleton of individual cells to collagen in the extracellular matrix. The mechanics of these systems under applied…
Non-affine deformation of semiflexible polymer and fiber networks
Sihan Chen, Tomer Markovich, Fred C. MacKintosh
Networks of semiflexible or stiff polymers such as most biopolymers are known to deform inhomogeneously when sheared. The effects of such non-affine deformation have been shown to…
Motor-free contractility of active biopolymer networks
Sihan Chen, Tomer Markovich, Fred C. MacKintosh
Contractility in animal cells is often generated by molecular motors such as myosin, which require polar substrates for their function. Motivated by recent experimental evidence of…
Strain-controlled critical slowing down in the rheology of disordered networks
Jordan L. Shivers, Abhinav Sharma, Fred C. MacKintosh
Networks and dense suspensions frequently reside near a boundary between soft (or fluid-like) and rigid (or solid-like) regimes. Transitions between these regimes can be driven by…
