TL;DR: This work presents a method based on magnetic tweezers; in combination with Stokesian dynamics and Boundary Integral Method calculations, this method allows the simultaneous measurement of the magnetic moments of multiple single bacteria.
Journal ArticleDOI
Cross-stream migration of asymmetric particles driven by oscillating shear
TL;DR: In this article, the authors study the dynamics of asymmetric deformable particles in oscillatory, linear shear flow, and they show that cross-stream migration occurs for asymmetric elastic particles even in linear Shear flow if the shear rate varies in time.
Journal ArticleDOI
Cross-stream transport of asymmetric particles driven by oscillating shear
TL;DR: In this article, the authors study the dynamics of asymmetric deformable particles in oscillatory, linear shear flow, and they show that cross-stream migration occurs for asymmetric elastic particles even in linear Shear flow if the shear rate varies in time.
Journal ArticleDOI
Focusing and splitting streams of soft particles in microflows via viscosity gradients.
TL;DR: This work describes a new mechanism of cross-streamline migration by using soft capsules with a spherical equilibrium shape, which is explained by analytical considerations, Stokesian dynamics simulations with a generalized Oseen tensor and lattice-Boltzmann simulations.
Journal ArticleDOI
Migration reversal of soft particles in vertical flows
TL;DR: In this paper, non-neutrally buoyant soft particles in vertical microflows are investigated and a reversal of the vertical flow direction and the related shear gradient is observed.
