Microfluidic blood cell sorting using the Fahraeus effect. (a) In a 5.5-mm long rectangular, straight microchannel leukocytes will be marginated to the edge, while more flexible red blood cells (RBCs) are concentrated in the center. (b) Using a bifuricated channel, one can sample and enrich white blood cells (WBCs), which are indicated by arrows. (c) The separation process is determined by both size and deformability of the WBC, compared with RBC. Reprinted with permission from Reference 60. ©2005, American Chemical Society.
