1. A method for screening candidate drugs for iontophoretic delivery, comprising:
- applying an alternating current to a bulk solution comprising at least one drug candidate;
measuring an impedance response of the bulk solution comprising the at least one drug candidate; and
ranking the at least one drug candidate for suitability for iontophoretic delivery based in part on the measured impedance response of the bulk solution comprising the at least one drug candidate.
