Abstract: The present invention provides an apparatus for conducting an assay in a microfluidic system comprising magnetic beads, said apparatus comprising: a platform upon which a microfluidic system can be mounted, one or more actuators having a magnet, configured to directly influence movement of magnetic beads housed within a microfluidic system when a microfluidic system is mounted on said platform, and a control means configured to control relative movement of the one or more magnets, and a microfluidic system when mounted, to enable the magnet to trace a desired path across a mounted microfluidic system, said magnet being positionable at any x- and y-coordinates of a mounted microfluidic system, wherein said apparatus further comprises: a) at least one rotary actuator configured to enable magnet movement in an x-axis, and/or b) a means for moving a mounted microfluidic system in a stepwise fashion.

Abstract: A system for conducting an assay comprises a power source (16), a controller (13) for controlling the assay and a plurality of assay units (14) operatively connected to one another such that the controller can communicate with the assay units and the system is capable of conducting the assay. An assay device comprises a substantially circular body (24) having a plurality of chambers in fluid connection such that fluid can pass between said chambers and a central hub (200) having a sample inlet (202) disposed therein for receiving a sample.
