Abstract

A microfluidic detection system for micrometer-sized entities, such as biological cells, includes a detector component incorporating a plate with a plurality of opening, the plate separating two chambers, one in communication with a fluid source containing target cells bound to magnetic beads. The openings are sized to always permit passage of the magnetic beads therethrough into a lower one of the chambers and are further sized to always prevent passage of the target cells from the upper one of the chambers. The detector component further includes a magnet positioned to pull unbound magnetic beads through the openings and to capture target cells bound to magnetic beads on the surface of the plate. The microfluidic detection system includes a pump flowing the fluid through the detector component at high flow rates of milliliters per minute for high throughput detection of target cells.
