Dynamic Clustering and Chemotactic Collapse of Self-Phoretic Active Particles

Dynamic clustering and chemotactic collapse of self-phoretic active particles.

Recent experiments with self-phoretic particles at low concentrations show a pronounced dynamic clustering [I. Theurkauff et al., Phys. Rev. Lett. 108, 268303 (2012)]. We model this situation by taking into account the translational and rotational diffusiophoretic motion, which the active particles perform in their self-generated chemical field. Our Brownian dynamics simulations show pronounced...

Chemotactic collapse and mesenchymal morphogenesis.

We study the effect of chemotactic signaling among mesenchymal cells. We show that the particular physiology of the mesenchymal cells allows one-dimensional collapse in contrast to the case of bacteria, and that the mesenchymal morphogenesis represents thus a more complex type of pattern formation than those found in bacterial colonies. We compare our theoretical predictions with recent in vitr...
