Probing the screening of the Casimir interaction with optical tweezers

We measure the colloidal interaction between two silica microspheres in an aqueous solution in the distance range from 0.2 to 0.5μm with the help of optical tweezers. When employing a sample with a low salt concentration, the resulting interaction is dominated by the repulsive double-layer interacti...
