Electrical Sensing of sickled red blood cells subpopulations in microfluidic device

This paper discusses the electrical sensing of red blood cell (RBC) rigidity due to Hemoglobin S (HbS) polymerization in sickle cell disease. For this purpose sickle RBCs subpopulations, differentiated by cell density, were flown through a microfluidic device equipped with integrated microelectrodes. Differences in transit time and electrical blockade were observed and analyzed.
