Intracellular rheology of red blood cells

The characterisation of erythrocyte stiffness and its heterogeneity in a blood sample is a key parameter for describing erythrocyte pathologies. I will present a method for probing the intracellular rheology of red blood cells based on molecular rotors, which are fluorescent probes sensitive to viscosity in viscous fluids. I will illustrate the interest of this approach in the context of red cell pathologies such as sickle cell anaemia. A. Briole, T. Podgorski & B.
