Abstract
A CD-based device for separating plasma from whole blood includes a substrate, a sedimentation chamber disposed in the substrate, and a collection chamber disposed in the substrate and in fluidic communication with the sedimentation chamber through a siphon channel. The sedimentation chamber includes a plurality of finger-like structures disposed along a radially outward edge of the sedimentation chamber, and protruding radially inward relative to the axis of rotation of the substrate. A method for separating plasma from whole blood using the CD-based device includes introducing a blood sample into the sedimentation chamber, rotating the substrate about an axis of rotation at a first rotational speed to separate the plasma from blood cells, and rotating the substrate about the axis of rotation at a second rotational speed, which is lower than the first rotational speed, to move the plasma from the sedimentation chamber into the collection chamber.
