The chiral beat of algal flagella: force and torque via imaging
Laurence G. Wilson, Martin A. Bees
Flagella allow eukaryotic cells to move and pump fluid. We present the first three-dimensional, time-resolved imaging of the flagellar waveform of Chlamydomonas reinhardtii, a mode…
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…
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…
Gyrotactic swimmer dispersion in pipe flow: testing the theory
O. A. Croze, R. N. Bearon, M. A. Bees
Suspensions of microswimmers are a rich source of fascinating new fluid mechanics. Recently we predicted the active pipe flow dispersion of gyrotactic microalgae, whose orientation…
Resonant alignment of microswimmer trajectories in oscillatory shear flows
Alexander Hope, Ottavio A. Croze, Wilson C. K. Poon +2
Oscillatory flows are commonly experienced by swimming microorganisms in the environment, industrial applications and rheological investigations. We experimentally characterise the…
Biased swimming cells do not disperse in pipes as tracers: a population model based on microscale behaviour
R. N. Bearon, M. A. Bees, O. A. Croze
There is much current interest in modelling suspensions of algae and other micro-organisms for biotechnological exploitation, and many bioreactors are of tubular design. Using gene…
