Axisymmetric spheroidal squirmers and self-diffusiophoretic particles
Ruben Poehnl, Mihail N. Popescu, William E. Uspal
We study, by means of an exact analytical solution, the motion of a spheroidal, axisymmetric squirmer in an unbounded fluid, as well as the low Reynolds number hydrodynamic flow as…
Shape-dependent guidance of active Janus particles by chemically patterned surfaces
W. E. Uspal, M. N. Popescu, M. Tasinkevych +1
Self-phoretic Janus particles move by inducing -- via non-equilibrium chemical reactions occurring on their surfaces -- changes in the chemical composition of the solution in which…
Topographical pathways guide chemical microswimmers
Juliane Simmchen, Jaideep Katuri, William E. Uspal +3
Achieving control over the directionality of active colloids is essential for their use in practical applications such as cargo carriers in microfluidic devices. So far, guidance o…
