Abstract
Front Microrheology is a technique developed to track the velocity of the fluid-air interface inside a microfluidics channel and determine the viscosity of the fluid. We use this technique to study the rheological properties of blood. These properties of blood depend highly on the properties of its red blood cells concentration, membrane elasticity and aggregation. These properties affect the viscosity of blood, as well as its shear thinning behavior. Using front microrheology technique, we determine the viscosity of different samples of blood. We propose a model able to predict the health conditions of blood samples by introducing a specific coefficient taking into account the hematocrit and the biomechanical properties of the red blood cells.
