We describe a novel method to prepare monodisperse Pickering emulsions. We start with classical surfactant-stabilized oil-in-water emulsions, which are sheared and size fractionated to attain monodispersity. Then, the surfactant is removed by a dialysis method and simultaneously replaced by solid particles. We obtain stable Pickering emulsions of the same size distribution as the initial surfactant-stabilized emulsion.
