26 Aug 2003 | | Subject: | Soft Condensed Matter; Cell Behavior; Subcellular Processes | cond-mat.soft q-bio.CB q-bio.SC | | Affiliation: | Raman Instt, Bangalore), Sriram Ramaswamy (IISc, Bangalore), Madan Rao (Raman Instt and NCBS, Bangalore) and R. Aditi Simha (MPI-PKS, Dresden | | Abstract: | We study the interplay of activity, order and flow through a set of coarse-grained equations governing the hydrodynamic velocity, concentration and stress fields in a suspension of active, energy-dissipating particles. We make several predictions for the rheology of such systems, which can be tested on bacterial suspensions, cell extracts with motors and filaments, or artificial machines in a fluid. The phenomena of cytoplasmic streaming, elastotaxis and active mechanosensing find natural explanations within our model. | | Source: | arXiv, cond-mat/0308529 | | Other source: | [GID 503759] pmid15089176 | | Services: | Forum | Review | PDF | Favorites | |
