1. An active molecule delivery system comprising:
a first substrate comprising:
a plurality of driving electrodes,
a dielectric layer covering the plurality of electrodes, and
a first hydrophobic layer coveting the dielectric layer;
a second substrate comprising:
a common electrode,
a second hydrophobic layer covering the common electrode;
a spacer separating the first and second substrates and creating a microfluidic region between the first and second substrates;
a plurality of reservoirs in fluidic communication with the plurality of driving electrodes;
a porous diffusion layer coupled to the first substrate on a side of the substrate opposed to the first hydrophobic layer;
a plurality of passages providing fluidic communication between the hydrophobic layer and the porous diffusion layer, wherein each of the plurality of reservoirs is in fluidic communication with only one passage, thereby providing an exclusive pathway of fluidic communication between each of the plurality of reservoirs and the porous diffusion layer; and
a controller operatively coupled to the driving electrodes and configured to provide a voltage gradient between at least two driving electrodes.
