Capillary flow of whole blood in microsystems: non-Newtonian blood behavior and substrate reagent-coating effect

Berthier J., Gosselin D., Huet M., Sabatte G., Cosnier M.L., Pouteau P., Cubizolles M., CEA-Leti (University Grenoble Alpes), FR

Introduction: The use of whole blood is a preferred solution for portable diagnostic and monitoring systems. We analyze here two particularities of microsystems for blood analysis: the blood non-Newtonian behavior, and the capillary flow in [...]

Combined effects of pump and capillary pressures for the filling of microchannel networks: the difficulty of synchronization

Berthier J., Diakite M.L., CEA-Leti (University Grenoble Alpes), FR

In this work, we first propose a model for the filling of a capillary tube driven by a pressure pump. It is shown that the filling time depends not only on the pump pressure but [...]
