    • Electromotive delivery of macromolecules can be provided using a delivery device including a first chamber for contacting a macromolecule delivery medium to a surface of a tissue or other anatomy of a patient; and a second chamber for contacting a receiving medium to the patient. A first electrode can be disposed in the first chamber so as to not directly contact the macromolecule delivery medium. A second medium having a buffering agent can be used to keep the first electrode from coming into direct contact with the macromolecule delivery medium. A second electrode can be disposed within the receiving medium in the second chamber such that the second electrode does not directly contact the patient. An electric field can be generated using the first and second electrodes in order to cause the macromolecule delivery medium to move into the tissue of interest from the first chamber of the delivery device.
    • 可以使用包括用于使大分子递送介质与组织的表面或患者的其他解剖结构接触的第一室的输送装置来提供大分子的电动势输送; 以及用于使接收介质接触患者的第二腔室。 第一电极可以设置在第一室中,以便不直接接触大分子输送介质。 可以使用具有缓冲剂的第二介质来保持第一电极不与大分子输送介质直接接触。 第二电极可以设置在第二室中的接收介质内,使得第二电极不直接接触患者。 可以使用第一和第二电极产生电场,以便使大分子递送介质从输送装置的第一室移动到感兴趣的组织中。
