The role of tumbling in bacterial scattering at convex obstacles
Theresa Jakuszeit, Ottavio A. Croze
Active propulsion, as performed by bacteria and Janus particles, in combination with hydrodynamic interaction results in the accumulation of bacteria at a flat wall. However, in mi…
Phototgyrotactic concentration of a population of swimming microalgae across a porous layer
Praneet Prakash, Ottavio A. Croze
The light environment controls the swimming of microalgae through a light-seeking and avoiding behaviour, which is known as phototaxis. In this work, we exploit phototaxis to contr…
Migration and accumulation of bacteria with chemotaxis and chemokinesis
Theresa Jakuszeit, James Lindsey-Jones, François J. Peaudecerf +1
Bacteria can chemotactically migrate up attractant gradients by controlling run-and-tumble motility patterns. In addition to this well-known chemotactic behaviour, several soil and…
Helical and oscillatory microswimmer motility statistics from differential dynamic microscopy
Ottavio A. Croze, Vincent A. Martinez, Theresa Jakuszeit +3
The experimental characterisation of the swimming statistics of populations of microorganisms or artificially propelled particles is essential for understanding the physics of acti…
Diffusion of active particles in a complex environment: Role of surface scattering
Theresa Jakuszeit, Ottavio A. Croze, Samuel Bell
Experiments have shown that self-propelled particles can slide along the surface of a circular obstacle without becoming trapped over long times. Using simulations and theory, we s…
Microbial mutualism at a distance: the role of geometry in diffusive exchanges
François J. Peaudecerf, Freddy Bunbury, Vaibhav Bhardwaj +4
The exchange of diffusive metabolites is known to control the spatial patterns formed by microbial populations, as revealed by recent studies in the laboratory. However, the matric…
