Journal ArticleDOI
Fluid Mechanics of Planktonic Microorganisms
TL;DR: In this paper, the authors discuss the fluid physics governing the locomotion and feeding of individual planktonic microorganisms (≤ 1 mm) and provide a review of the recent advances in this area.
Journal ArticleDOI
Dynamics of Enhanced Tracer Diffusion in Suspensions of Swimming Eukaryotic Microorganisms
Kyriacos C. Leptos,Jeffrey S. Guasto,Jerry P. Gollub,Jerry P. Gollub,Adriana I. Pesci,Raymond E. Goldstein +5 more
TL;DR: The role of flagellar beating in creating oscillatory flows that exceed brownian motion far from each swimmer is emphasized, with a time-dependent but self-similar probability distribution function of displacements consisting of a gaussian core and robust exponential tails.
Journal ArticleDOI
Bacterial transport suppressed by fluid shear
TL;DR: It is shown that hydrodynamic shear, which creates forces and torques on bacterial suspensions, stimulates the attachment of bacteria to surfaces and seriously hinders chemotaxis.
Journal ArticleDOI
Bacteria can exploit a flagellar buckling instability to change direction
TL;DR: High-speed video microscopy and mechanical stability theory now show that cells propelled with a single flagellum change direction with a flick-like motion that exploits a buckling instability.
Journal ArticleDOI
Oscillatory Flows Induced by Microorganisms Swimming in Two Dimensions
TL;DR: The first time-resolved measurements of the oscillatory velocity field induced by swimming unicellular microorganisms are presented, revealing complex time-dependent flow structures, and scales inversely with distance.
