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.
