Paper Abstract

The lateral migration of platelets and red blood cells in highly diluted suspensions was studied using a laser-Doppler velocimeter with microscopic resolution. The experiments were performed in a 100 micrometers width, rectangular flow channel of high aspect ratio. It was found that platelets tend to migrate towards an equilibrium position well away from the channel wall. This migration effect turns out to be identical to the so-called tubular pinch effect that is well- known for rigid spheres. Red blood cells, on the other hand, eventually accumulate in the center of the flow similar to deformable liquid droplets.
