Abstract
A transdermal delivery device to passively deliver active agents to a biological interface includes an active agent reservoir comprising a first active agent of a first polarity; an outer active agent membrane taking the form of an ion-exchange membrane of a second polarity, an interfacial layer having a plurality of freely diffusible monovalent co-ions of the first polarity and having a first side adjacent to the outer active agent membrane and a second side configured to contact a biological interface.
