Microfluidic device enables rapid particle separation
June 23rd, 2004
A novel device enables rapid separation of different-sized particles. Researchers in the United States developed "a microfluidic particle-separation device that makes use of the asymmetric bifurcation of laminar flow around obstacles." "A particle chooses its path deterministically on the basis of its size," explained L.R. Huang and coauthors at Princeton University. "All particles of a given size follow equivalent migration paths, leading to high resolution." "The microspheres of 0.8, 0.9, and 1.0 micrometers that were used to characterize the device were sorted in 40 seconds with a resolution of approximately 10 nanometers,...
