On continuum modeling of cell aggregation phenomena
Soheil Firooz, Stefan Kaessmair, Vasily Zaburdaev +2
Cellular aggregates play a significant role in the evolution of biological systems such as tumor growth, tissue spreading, wound healing, and biofilm formation. Analysis of such bi…
Liquid phase separation controlled by pH
Omar Adame-Arana, Christoph A. Weber, Vasily Zaburdaev +2
We present a minimal model to study liquid phase separation in a fixed pH ensemble. The model describes a mixture composed of macromolecules that exist in three different charge st…
How bacterial cells and colonies move on solid substrates
Wolfram Pönisch, Christoph A. Weber, Vasily Zaburdaev
Many bacteria rely on active cell appendages, such as type IV pili, to move over substrates and interact with neighboring cells. Here, we study the motion of individual cells and b…
Chemotactic drift speed for bacterial motility pattern with two alternating turning events
E. V. Pankratova, A. I. Kalyakulina, M. I. Krivonosov +3
Bacterial chemotaxis is one of the most extensively studied adaptive responses in cells. Many bacteria are able to bias their apparently random motion to produce a drift in the dir…
Elasticity-based polymer sorting in active fluids: A Brownian dynamics study
Jaeoh Shin, Andrey G. Cherstvy, Won Kyu Kim +1
While the dynamics of polymer chains in equilibrium media is well understood by now, the polymer dynamics in active non-equilibrium environments can be very different. Here we stud…
Relative distance between tracers as a measure of diffusivity within moving aggregates
Wolfram Pönisch, Vasily Zaburdaev
Tracking of particles, be it a passive tracer or an actively moving bacterium in the growing bacterial colony, is a powerful technique to probe the physical properties of the envir…
