The manipulator includes a support and at least one member affixed to and extending away from the support. The member has at least two differentially activatable electrodes. The electrodes are configured to establish a first electromagnetic field in vivo between selected electrodes sufficient to manipulate a molecule relative to a target tissue and to establish a second, typically higher, electromagnetic field sufficient to cause transient permeability of a cell membrane within the target tissue. One method of using the device is for enhancing the delivery of a molecule into a tissue site. In a related embodiment the device may be used to cause the electromigration of at least two components of a multicomponent reactive system into apposition to permit a reaction to occur at a desired target tissue site. The target tissue may comprise a tumor, organ, or wound site.
