Physical phase field model for phagocytosis
Benjamin Winkler, Mohammad Abu Hamed, Alexander A. Nepomnyashchy +1
We propose and study a simple, physical model for phagocytosis, i.e. the active, actin-mediated uptake of micron-sized particles by biological cells. The cell is described by the p…
The role of the nucleus for cell mechanics: an elastic phase field approach
Robert Chojowski, Ulrich S. Schwarz, Falko Ziebert
The nucleus of eukaryotic cells typically makes up around 30% of the cell volume and has significantly different mechanics, which can make it effectively up to ten times stiffer th…
Coarse-graining the vertex model and its response to shear
Gloria Triguero-Platero, Falko Ziebert, Luis L. Bonilla
Tissue dynamics and collective cell motion are crucial biological processes. Their biological machinery is mostly known, and simulation models such as the "active vertex model" (AV…
Emergent conformational properties of end-tailored transversely propelling polymers
K. R. Prathyusha, Falko Ziebert, Ramin Golestanian
We study the dynamics and conformations of a single active semiflexible polymer whose monomers experience a propulsion force perpendicular to the local tangent, with the end beads…
How Influenza's Spike Motor Works
Falko Ziebert, Igor M. Kulić
While often believed to be a passive agent that merely exploits its host's metabolism, influenza virus has recently been shown to actively move across glycan-coated surfaces. This…
Dynamics of Fiberboids
Antony Bazir, Arthur Baumann, Falko Ziebert +1
Fiberboids are active filaments trapped at the interface of two phases, able of harnessing energy (and matter) fluxes across the interface in order to produce a rolling-like self-p…
