In one aspects of the invention, a microcapsule includes a film encapsulating a material. The film is formed by complexation of at least two mutually attractive components initially present in an aqueous dispersion comprising a continuous phase and a dispersed phase. The at least one first component is initially present in the continuous phase and the at least one second component is initially present in the dispersed phase. According to another aspect of the invention, provided is a process for forming microcapsules including the step of injecting a dispersed phase having at least a first component into a continuous phase having at least a second component, where the first component and the second component are mutually attractive, such that a film is formed by complexation of the first charged component and the second charged component.
