New blood research research from Y.C. Kim et al outlined

Published in Blood Weekly, May 20th, 2010

"This paper presents a capillary-driven microfluidic device that uses surfactant-added poly(dimethylsiloxane) (PDMS) to extract plasma from the blood without any external driving force. On the basis of the capillary phenomenon and filtration effect, plasma can be extracted through a planar crossflow filter using surfactant-added hydrophilic PDMS and SU-8-based microstructures," scientists in South Korea report.

"Because of the intrinsic hydrophobicity of PDMS, it is difficult to transport fluid in a PDMS microchannel using capillary action alone. In this study, we fabricated a microfluidic device with surfactant-added PDMS. The wetting property of PDMS was modified to...
