Abstract: The invention provides a microfluidic system comprising a cartridge coupled to a motor and adapted to move a fluid sample to a plurality of locations on the cartridge. The cartridge comprises a chevron shaped or substantially V shaped reaction chamber having at least three zones, a first zone positioned near the apex of the V shaped reaction chamber to define a detection zone, a second zone positioned near a first end of the V shaped reaction chamber and a third zone positioned near a second end of the V shaped reaction chamber. The motor and a control module is configured to provide a combination of centrifugal force and gravitational force to move said fluid sample between at least three zones.

Abstract: The invention provides a microfluidic system comprising a cartridge coupled to a motor and adapted to move a fluid sample to a plurality of locations on the cartridge. The cartridge is configured to rotate on an inclined plane, thus providing for a combination of centrifugal force and gravitational force to move the fluid sample within the cartridge. Such a configuration may facilitate the performance of a sequential assay by making it easier to move a fluid radially inwards within the cartridge. The cartridge provided comprises a reaction chamber (15) with at least three zones within the chamber: a first zone (Zone A) is positioned radially outward comprises a cuvette (45) for optical measurement; a second and third zones (Zones B and C) are positioned closer to a centre of rotation (25) and may comprise dried reagents spots (R1, R2).

Abstract: A microfluidic system for processing biological samples comprising a holding chamber adapted for holding a fluid and to be rotated on a platform, said holding chamber comprising an outlet through which fluid flow is controlled by an acceleration-primed valve system, wherein the acceleration-primed valve system comprises a capillary valve and an outlet channel. The invention provides a novel valving system, which retains fluids at low angular velocities, removes the need for hydrophilic surfaces, minimises disc real-estate and optimises certain microfluidic processes done in the holding chamber.
