Abstract
Methods for preparing capsules, such as micro- and/or nanocapsules from all-aqueous emulsions are described herein. The method includes mixing, combining, or contacting a first electrically charged phase containing a first solute with at least an optionally charged second phase containing a second solute. The solutes are incompatible with each other. The electrostatic forces between the two solutions induce the formation of droplets of a dispersed phase in a continuous phase. The droplets are then solidified to form the capsules.
