Bacteria collective motion is scale-free
Benjamin Perez-Estay, Vincent Martinez, Carine Douarche +7
Suspensions of swimming bacteria interact hydrodynamically over long ranges, organizing themselves into collective states that drive large-scale chaotic flows, often referred to as…
Characterization and Control of the Run-and-Tumble Dynamics of {\it Escherichia Coli}
Christina Kurzthaler, Yongfeng Zhao, Nan Zhou +8
We characterize the full spatiotemporal gait of populations of swimming {\it Escherichia coli} using renewal processes to analyze the measurements of intermediate scattering functi…
Escherichia coli as a model active colloid: a practical introduction
Jana Schwarz-Linek, Jochen Arlt, Alys Jepson +6
The flagellated bacterium Escherichia coli is increasingly used experimentally as a self-propelled swimmer. To obtain meaningful, quantitative results that are comparable between d…
Flagellated bacterial motility in polymer solutions
Vincent A. Martinez, Jana Schwarz-Linek, Mathias Reufer +3
It is widely believed that the swimming speed, , of many flagellated bacteria is a non-monotonic function of the concentration, , of high-molecular-weight linear polymers in…
Swimming in a Crystal:
Aidan T. Brown, Ioana D. Vladescu, Angela Dawson +4
We study catalytic Janus swimmers and Escherichia coli bacteria swimming in a two-dimensional colloidal crystal. The Janus swimmers orbit individual colloids and hop between colloi…
Filling an emulsion drop with motile bacteria
I. D. Vladescu, E. J. Marsden, J. Schwarz-Linek +6
We have measured the spatial distribution of motile Escherichia coli inside spherical water droplets emulsified in oil. At low cell concentrations, the cell density peaks at the wa…
Phase separation and rotor self-assembly in active particle suspensions
J. Schwarz-Linek, C. Valeriani, A. Cacciuto +4
Adding a non-adsorbing polymer to passive colloids induces an attraction between the particles via the `depletion' mechanism. High enough polymer concentrations lead to phase separ…
