Confinement controls bacterial spreading at all scales

Renaud Baillou, Marta Pedrosa Garcia-Moreno, Quentin Guigue +5

Navigation of microorganisms is controlled by internal processes ultimately sensitive to mechanical or chemical signaling encountered along the path. In many natural environments,…

Molecular Dynamics Simulations of Microscopic Structural Transition and Macroscopic Mechanical Properties of Magnetic Gels

Xuefeng Wei, Gaspard Junot, Ramin Golestanian +4

Magnetic gels with embedded micro/nano-sized magnetic particles in crosslinked polymer networks can be actuated by external magnetic fields, with changes in their internal microsco…

Bidirectional Zigzag Growth from Clusters of Active Colloidal Shakers

Gaspard Junot, Andrés Javier Manzano González, Pietro Tierno

Driven or self-propelling particles moving in viscoelastic fluids recently emerge as novel class of active systems showing a complex yet rich set of phenomena due to the non-Newton…

Large scale zigzag pattern emerging from circulating active shakers

Gaspard Junot, Marco De Corato, Pietro Tierno

We report the emergence of large zigzag bands in a population of reversibly actuated magnetic rotors that behave as active shakers, namely squirmers that shake the fluid around the…

Collective hydrodynamic transport of magnetic microrollers

Gaspard Junot, Andrejs Cebers, Pietro Tierno

We investigate the collective transport properties of microscopic magnetic rollers that propel close to a surface due to a circularly polarized, rotating magnetic field. The applie…

Run-to-Tumble Variability Controls the Surface Residence Times of Bacteria

Gaspard Junot, Thierry Darnige, Anke Lindner +6

Motile bacteria are known to accumulate at surfaces, eventually leading to changes in bacterial motility and bio-film formation. We use a novel two-colour, three-dimensional Lagran…

Single-Trajectory Characterization of Active Swimmers in a Flow

Gaspard Junot, Eric Clément, Harold Auradou +1

We develop a maximum likelihood method to infer relevant physical properties of elongated active particles. Using individual trajectories of advected swimmers as input, we are able…

Swimming bacteria in Poiseuille flow: the quest for active Bretherton-Jeffery trajectories

Gaspard Junot, Nuris Figueroa-Morales, Thierry Darnige +4

Using a 3D Lagrangian tracking technique, we determine experimentally the trajectories of non-tumbling E. coli mutants swimming in a Poiseuille flow. We identify a typology of traj…

Oscillatory surface rheotaxis of swimming E. coli bacteria

Arnold Mathijssen, Nuris Figueroa-Morales, Gaspard Junot +3

Bacterial contamination of biological conducts, catheters or water resources is a major threat to public health and can be amplified by the ability of bacteria to swim upstream. Th…

3D spatial exploration by E. coli echoes motor temporal variability

Nuris Figueroa-Morales, Rodrigo Soto, Gaspard Junot +5

Unraveling bacterial strategies for spatial exploration is crucial for understanding the complexity in the organization of life. Bacterial motility determines the spatio-temporal s…
