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…
