Efficiency test on the experimental design of micromachined blood separation system based on Zweifach-Fung effect

When aiming a complete microfluidic analysis system for human blood tests the blood plasma separation should be preferably also integrated in the device. The sensitivity of the analysis is significantly affected by the sample quality, so in this work the efficiency of the Zweifach-Fung effect based microfluidic separation systems was characterized. The microstructures were fabricated by simple replication in polydimethylsilixane applying SU-8 photoresist master beside extensive variation of the geometric parameters.
