Atomic force microscopy has been used to probe the effect that both adsorbing and non-adsorbing polymers have on the force interactions between oil droplets suspended in aqueous solution. At low polymer concentrations depletion effects were found to predominate in both cases. At higher polymer concentrations steric effects took over which could cause both repulsive and attractive interactions between the droplets.
