Flagellar Kinematics and Swimming of Algal Cells in Viscoelastic Fluids
Boyang Qin, Arvind Gopinath, Jing Yang +2
The motility of microorganisms is influenced greatly by their hydrodynamic interactions with the fluidic environment they inhabit. We show by direct experimental observation of the…
Particle diffusion in active fluids is non-monotonic in size
Alison E. Patteson, Arvind Gopinath, Prashant K. Purohit +1
We experimentally investigate the effect of particle size on the motion of passive polystyrene spheres in suspensions of Escherichia coli. Using particles covering a range of sizes…
Persistence of activity in noisy motor-filament assemblies
Raghunath Chelakkot, Arvind Gopinath, L. Mahadevan
Long, elastic filaments cross-linked and deformed by active molecular motors occur in various natural settings. The overall macroscopic mechanical response of such a composite netw…
Persistence of strain in motor-filament assemblies
Arvind Gopinath, Raghunath Chelakkot, L. Mahadevan
Crosslinked semi-flexible and flexible filaments that are actively deformed by molecular motors occur in various natural settings, such as the ordered eukaryotic flagellum, and the…
