Abstract

Platelet separation from blood is fundamental technique for biochemical analyses. In this article, we proposed a method to collect platelets from whole blood utilizing standing surface acoustic waves (SSAWs) in a microfluidic device. A polydimethylsiloxane (PDMS) microfluidic device was integrated with interdigitated transducers (IDTs) on a piezoelectric substrate. Whole blood sample was hydrodynamically focused by sheath flow from side inlets. Pressure nodes were designed to locate at side walls, thereby collecting platelets with minimum shear effect. Finally, the RBC clearance ratio from whole blood was found to be 99% and the purity of platelets was close to 98%.
