Abstract

A device for delivery of one or more active agents to a biological interface includes a matrix having at least one dendritic polymer or arborol. In certain embodiments, the dendritic polymer or arborol self-assembles to form a matrix having aqueous pores or cavities to contain and allow transport of active agents or ions. In particular aspects, the device is an iontophoretic device. In certain aspects, the iontophoretic device may include an active electrode assembly having an active agent holding portion or reservoir; and a non-active electrode assembly.
