Oscillatory, non-progressing flows induce directed cell motion
Winfried Schmidt, Andre Förtsch, Matthias Laumann +1
We present a deformation-dependent propulsion phenomenon for soft particles such as cells in microchannels. It is based on a broken time reversal symmetry generated by a fast forwa…
Focusing and splitting of particle streams in microflows via viscosity gradients
Matthias Laumann, Walter Zimmermann
Microflows are intensively used for investigating and controlling the dynamics of particles, including soft particles such as biological cells and capsules. A classic result is the…
Engineering passive swimmers by shaking liquids
M. Laumann, A. Förtsch, E. Kanso +1
The locomotion and design of microswimmers are topical issues of current fundamental and applied research. In addition to numerous living and artificial active microswimmers, a pas…
Migration reversal of soft particles in vertical flows
Andre Förtsch, Matthias Laumann, Diego Kienle +1
Non-neutrally buoyant soft particles in vertical microflows are investigated. We find, soft particles lighter than the liquid migrate to off-center streamlines in a downward Poiseu…
Cross-stream transport of asymmetric particles driven by oscillating shear
Matthias Laumann, Paul Bauknecht, Stephan Gekle +2
We study the dynamics of asymmetric, deformable particles in oscillatory, linear shear flow. By simulating the motion of a dumbbell, a ring polymer, and a capsule we show that cros…
