    Multiphase liquid droplets consisting of three connected but immiscible liquid phases are demonstrated. The droplets have designer geometries stabilized by surface energy patterns; aqueous phases prefer contact with hydrophilic surface while organic phases prefer contact with hydrophobic areas. The multiphase droplets are applied for liquid-liquid-liquid extraction.
