Abstract
A digital microfluidics (DMF) device can be used to extract plasma from whole blood and manipulate the extracted plasma. The device can have a plasma separation membrane disposed between a sample inlet and sample outlet that leads into the DMF device. Once the plasma contacts the actuation electrodes of the DMF device, the plasma can be actively extracted from the whole blood sample by actuating the actuation electrodes to pull the plasma through plasma separation membrane.
