The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

© 2015 IEEE. A surface acoustic wave (SAW) based microfluidic device for human blood plasma separation has been proposed and experimentally demonstrated. The microchannel consists of a constriction-expansion section and a bifurcation channel. The effect of constriction-expansion transition on the blood separation has been investigated with and without SAW. An acoustic power of 20.43 dBm is found enough for plasma isolation from 50× diluted human blood at a flow rate of 0.006μL/min. Higher acoustic power is required for the blood separation at higher flow rate. A diagram of combined working conditions is obtained for guiding the successful blood/plasma separation in the microfluidic chip of given design.
