Micro-rheology near fluid interfaces
Using optical trapping, we have measured anisotropic and distance-dependent mobility of a colloidal particle near high surface tension fluid-fluid interfaces. These experimental results show that the parallel mobility is enhanced near a high surface tension liquid-gas surface, which is consistent with hydrodynamic predictions for a surface that does not support a stress, and that the parallel mobility is suppressed near a high surface tension liquid-liquid surface, consistent with a no-slip...[Show more]
