Active molecule delivery system, wherein the active molecule is released on demand and / or a variety of different active molecules are delivered from the same system and / or different concentrations of active molecule are delivered from the same system. An active molecule delivery system that can be. The active molecule delivery system comprises a plurality of microcells, which are filled with a medium for delivering the active molecules. In some embodiments, the medium comprises a mixture of active molecules scattered in a first charged phase and a second phase, the second phase being oppositely charged or uncharged, And is immiscible with the first phase. If the medium comprises a chargeable first phase, the first phase can be moved adjacent to or away from the porous diffusion layer to control the delivery rate. |
