We consider only the in-plane motion of the particles; this is motivated by the fact that, in the experiments, we did not observe any tendency of the silica particles to lift-off (and by the fact that the sedimentation velocity of the silica particle (≈8, Accordingly, the in-plane motion of a particle at an in-plane distance, The first equality identifies two contributions to the motion of the particle: the response to the spatial gradients in chemical composition of the solution (due to the catalytic enzymatic reaction at the patch location), i.e., phoresis, and the drag by the ambient hydrodynamic flow, Due to the no-slip boundary condition at the surface of the wall, the magnitude of the flow, We are thus left with only the phoretic and osmotic terms, which corresponds to a classical problem of phoresis of a spherical particle in externally imposed gradients in chemical composition and under geometrical confinement [, To apply these existing results it is thus necessary to determine the chemical field induced by the catalytic reaction at the enzyme.
