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…
Calculating the motion of highly confined, arbitrary-shaped particles in Hele-Shaw channels
Bram Bet, Rumen Georgiev, William Uspal +3
We combine theory, numerical calculations, and experiments to accurately predict the motion of anisotropic particles in shallow microfluidic channels, in which the particles are st…
Cross-stream migration of active particles
Jaideep Katuri, William E. Uspal, Juliane Simmchen +2
For natural microswimmers, the interplay of swimming activity and external flow can promote robust motion, e.g. propulsion against ("upstream rheotaxis") or perpendicular to the di…
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…
