Experimental Observation of Flow Fields Around Active Janus Spheres
Andrew I. Campbell, Stephen J. Ebbens, Pierre Illien +1
The hydrodynamic flow field around a catalytically active colloid is probed using particle tracking velocimetry both in the freely swimming state and when kept stationary with an e…

Helical paths, gravitaxis, and separation phenomena for mass-anisotropic self-propelling colloids: experiment versus theory
Andrew I. Campbell, Raphael Wittkowski, Borge ten Hagen +2
The self-propulsion mechanism of active colloidal particles often generates not only translational but also rotational motion. For particles with an anisotropic mass density under…
