Two-dimensional nature of the active Brownian motion of catalytic microswimmers at solid and liquid interfaces

Two-dimensional nature of the active Brownian motion of catalytic microswimmers at solid and liquid interfaces

Colloidal particles equipped with platinum patches can establish chemical gradients in H _2 O _2 -enriched solutions and undergo self-propulsion due to local diffusiophoretic migration. In bulk (3D), this class of active particles swim in the direction of the surface heterogeneities introduced by th...
