A microfluidic device to statistically determine the distribution of sickle red cell subpopulations using bioimpedance
Résumé
Bioimpedance measurements using microfluidic systems play an increasingly important role in cell analysis. In this paper, a microfluidic device mimicking the vasculature, in particular blood microcapillaries, and equipped with electrodes for bioimpedance sensing is described. Red blood cells, from patients suffering from sickle cell disease, were analyzed and discriminated in this device according to the physical parameters. The statistical position of different subpopulations on the Gaussian distribution of the whole sickle cell population was analyzed. A discrimination between sickle cell subpopulations, related to different density states, was achieved.
