Lab-on-a-chip based blood plasma separation

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.
