      abstract     = {Bacteria such as Escherichia coli swim along circular
                      trajectories adjacent to surfaces. Thereby, the orientation
                      (clockwise, counterclockwise) and the curvature depend on
                      the surface properties. We employ mesoscale hydrodynamic
                      simulations of a mechano-elastic model of E. coli, with a
                      spherocylindrical body propelled by a bundle of rotating
                      helical flagella, to study quantitatively the curvature of
                      the appearing circular trajectories. We demonstrate that the
                      cell is sensitive to nanoscale changes in the surface slip
                      length. The results are employed to propose a novel approach
                      to directing bacterial motion on striped surfaces with
                      different slip lengths, which implies a transformation of
                      the circular motion into a snaking motion along the stripe
                      boundaries. The feasibility of this approach is demonstrated
                      by a simulation of active Brownian rods, which also reveals
                      a dependence of directional motion on the stripe width.},
