Researchers have developed a cheap microfluidic device to
separate plasma from whole blood with efficiency similar to centrifugation. A filter at the top of a channel with blood flowing
upwards separated the fluid phase from the cells. Gravity-assisted
sedimentation prevented cells clogging the filter and subsequent hemolysis.
