Micro-Tug-of-War: A Selective Control Mechanism for Magnetic Swimmers
(American Physical SocietyPhysical Review Applied, 2016-06-30)
One of the aspirations for artificial microswimmers is their application in noninvasive medicine. For any practical use, adequate mechanisms enabling control of multiple artificial swimmers will be of paramount importance. ...
Flagellar flows around bacterial swarms
(American Physical SocietyPhysical Review Fluids, 2016)
Flagellated bacteria on nutrient-rich substrates can differentiate into a swarming state and move in dense swarms across surfaces. A recent experiment measured the flow in the fluid around an Escherichia coli swarm (Wu, ...
Phoretic flow induced by asymmetric confinement
(Cambridge University PressJournal of Fluid Mechanics, 2016-07-25)
Internal phoretic flows due to the interactions of solid boundaries with local chemical gradients may be created using chemical patterning. Alternatively, we demonstrate here that internal flows might also be induced by ...
Flow analysis of the low Reynolds number swimmer $\textit{C. elegans}$
(American Physical SocietyPhysical Review Fluids, 2016-09-09)
Swimming cells and microorganisms are a critical component of many biological processes. In order to better interpret experimental studies of low Reynolds number swimming, we combine experimental and numerical methods to ...
Elastohydrodynamic synchronization of adjacent beating flagella
(American Physical SocietyPhysical Review Fluids, 2016-11-01)
It is now well established that nearby beating pairs of eukaryotic flagella or cilia typically synchronize in phase. A substantial body of evidence supports the hypothesis that hydrodynamic coupling between the active ...
Can phoretic particles swim in two dimensions?
(American Physical SocietyPhysical Review E, 2016-12-16)
Artificial phoretic particles swim using self-generated gradients in chemical species (self-diffusiophoresis) or charges and currents (self-electrophoresis). These particles can be used to study the physics of collective ...
