    Abstract

    We demonstrate a novel, flexible and biocompatible method to pump liquid through microchannels without the use of an external pump. The pumping principle is based on the rotation of superparamagnetic microspheres around permalloy disks, driven by an external in-plane rotating magnetic field. By placing the permalloy disks close to the edge of the channel, a net flow of 9 μm/s was generated in the middle of the channel. This pumping principle is especially suited for flow controlled medium recirculation in culture chambers, opening ways towards portable, on-chip closed cell culturing [1].
