We address the problem of two-dimensional (2D) colloidal aggregation driven by an ac electrical field, by observing an aqueous dispersion of latex microspheres in contact with a conducting surface. Using micron-sized carboxylated polystyrene particles, we have systematically investigated the aggregation process, as a function of particle size and charge,(More)
2014 A new method is proposed to measure the curvature elastic modulus kc of a membrane, by observing the thermal induced fluctuations of the shape of a spherical vesicle. Observations of the liposomes were carried out under a microscospe working in the regime of Nomarski differential interference contrast. We show that the value of kc thus measured is the(More)
