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: The invention provides a high resolution, wide dynamic range, multi-colour detection platform for microfluidic analysers/instruments and methods. The detection platform uses multiple high gain semiconductor optical sensors for the detection of luminescence from cellular or biological samples. The digitized outputs from these sensors are combined and weighted in a signal processing unit, using pre-determined algorithms for each colour, which optimise the resolution in each of these high gain semiconductor optical sensors while extending the dynamic range of the detection platform.
