    • Methods of creating patterns on substrates are presented, and articles of manufacture resulting therefrom. One method comprises applying a first surface energy modifier (18) to an applicator (16) to form a coating on the applicator; contacting the coating (18) with a receiving member (4), the receiving member having a topography, the coating only contacting and remaining on at least some protrusions (8); exposing the first modified receiving member (22) to a second surface energy modifier (21), thereby forming a second modified receiving member (24) having surface modified recesses; applying a composition (26) comprising a polymeric material to the second modified receiving member (24), the composition substantially conforming to the topography of the surface modified protrusion's (8) and the surface modified recesses; and contacting the composition-coated, surface modified protrusions with a substrate (11) for a time and under conditions sufficient to transfer the polymeric material (26) on protrusions to the substrate (11). Because the surface energy of the sidewalls is lower than that on the protrusions, polymer dewetting from the sidewalls is promoted, which makes the polymer film discontinuous along the edges of patterns. Therefore, inked polymer patterns from the protrusions of the mold show very smooth edges and smaller dimensions compared to that of the mold.
    • 呈现在基板上形成图案的方法以及由此产生的制品。 一种方法包括将第一表面能量调节剂(18)施加到施用器(16)上以在施用器上形成涂层; 使所述涂层(18)与接收构件(4)接触,所述接收构件具有形貌,所述涂层仅接触并保留在至少一些突起(8)上; 将第一改进的接收构件(22)暴露于第二表面能量改性剂(21),从而形成具有表面改性凹槽的第二改进的接收构件(24); 将包含聚合物材料的组合物(26)施加到第二改性接收构件(24)上,该组合物基本上符合表面改性突起(8)和表面改性凹槽的形貌; 并且使组合物涂覆的表面改性的突起与衬底(11)接触足以将突起上的聚合物材料(26)转移到衬底(11)上的时间和条件。 由于侧壁的表面能低于突起上的表面能,因此促进了从侧壁的聚合物去湿,这使得聚合物膜沿着图案的边缘不连续。 因此,与模具相比,来自模具的凸起的上色聚合物图案显示出非常光滑的边缘和更小的尺寸。

    • An electrochemically actuated liquid delivering device which is capable of releasing specific volumes of liquid at desired flow rates. The device includes a sealed electrolytic chamber which is adapted to contain an electrolyte and has at least one pair of electrodes which are at least partially in contact with the electrolyte. It also has a liquid chamber formed of a rigid material which is housed at least partially within the electrolytic chamber and is adapted to contain a liquid. It has pressure transfer means separating the electrolytic chamber from the liquid chamber and administering means which is adapted to release the liquid from the liquid chamber under the influence of pressure applied to the liquid chamber. The device is arranged so that when current is passed through the electrolyte via the electrodes, gas is generated from the electrolyte thereby increasing pressure inside the electrolytic chamber. That increase in pressure is transferred to the liquid chamber via the pressure transfer means and a determinable amount of the liquid is released from the liquid chamber via the administering means. The device has particular application in liquid drug delivery systems such as insulin infusion.
