    dct:description """
              Rheology of high molecular weight polymer solutions at submicroscale is investigated, with a particular emphasis on the wall slip characterization. Our approach is to measure the velocity of a pressure-driven flow in sub-microchannels in order to determine an effective viscosity of fluids. We have been using fluorescence photobleaching as a non-invasive technique to evaluate the velocity of a pressure-driven flow in 175 to 4000 nm high channels. A striking reduction of the effective viscosity is observed with the confinement, as compared to the bulk one. Direct measurement of slip velocity in microchannels is performed, using z-resolved micro-Particle Image Velocimetry (PIV). This study enables to draw two important conclusions, which have never been experimentally demonstrated. Slippage of polymer solutions in the semi-dilute unentangled regime is greatly reduced by confinement. A distinction of bulk and surface phenomena seems no longer valid at the submicroscale. This experimental method is also adapted to the study of surfactant solutions flows at the submicroscale.
