    Abstract

    We report geometrically programmable bidirectional pumping in microchannels using magnetic microspheres which rotate around magnetic disks under influence of an external rotating magnetic field. Geometric programming of the pumping direction is obtained by locating the magnetic disks on the inside or the outside curve of a microchannel as shown in Figure 1. A second degree of freedom in pumping direction is offered by the rotation direction of the external field. Pumping rate is controlled by the rotational frequency.
