Elastic interactions compete with persistent cell motility to drive durotaxis
Subhaya Bose, Haiqin Wang, Xinpeng Xu +2
The directed migration of cells toward stiffer substrate regions or durotaxis is relevant to tissue development and tumor progression. Here, we introduce a phenomenological model f…
Collective states of active particles with elastic dipolar interactions
Subhaya Bose, Patrick S. Noerr, Ajay Gopinathan +2
Many types of mammalian cells exert active contractile forces and mechanically deform their elastic substrate, to accomplish biological functions such as cell migration. These subs…
Flagellar dynamics of a connected chain of active, Brownian particles
Raghunath Chelakkot, Arvind Gopinath, L. Mahadevan +1
Eukaryotic flagella are active structures with a complex architecture of microtubules, motor proteins and elastic links. They are capable of whiplike motions driven by motors slidi…
Viscoelastic flow transitions in abrupt planar contractions
Lars Geneiser, Arvind Gopinath, Robert Armstrong +1
We present experimental evidence of global viscoelastic flow transitions in 2:1, 8:1 and 32:1 planar contractions under inertia-less conditions. Light sheet visualization and laser…
Semi-permeable vesicles composed of natural clay
Anand B. Subramaniam, Jiandi Wan, Arvind Gopinath +1
We report a simple route to form robust, inorganic, semi-permeable compartments composed of montmorillonite, a natural plate-like clay mineral that occurs widely in the environment…
Transitions to Nematic states in homogeneous suspensions of high aspect ratio magnetic rods
A. Gopinath, L. Mahadevan, R. C. Armstrong
Isotropic-Nematic and Nematic-Nematic transitions from a homogeneous base state of a suspension of high aspect ratio, rod-like magnetic particles are studied for both Maier-Saupe a…
