Definitions

  • the present invention provides a device having a capsule suitable for implantation.
  • the device also includes a reservoir encapsulated by the capsule, wherein the reservoir is suitable for containing a therapeutic agent.
  • the device also includes a tiiania nanotube membrane on a titanium substrate, wherein the titanium substrate is attached to the capsule such that the titanium substrate is in contact with the reservoir, wherein the titania nanotube membrane comprises a plurality of titania nanotubes in fluid contact with the reservoir.
  • Figure 4 shows the chamber with anode inserted in the hole in the base of the chamber with the gasket side of the anode remaining in the chamber.
  • the internal diameter can be of from about 1 to 1000 nm, or from about 1 to about 100 nm, or from about 1 to about 50 nm, or from about 1 to about 20 nm. Tn some embodiments, the internal diameter can be of from about 10 nm to about 1000 nm.
  • the titama nanotube membrane of the device of the present invention can be prepared by any suitable method, namely by growing the titania nanotubes on a titanium substrate, followed by etching the back side of the titanium substrate, the side opposite the titania nanotubes, until the inner portion of a subset of the nanotubes is exposed.
  • the present invention provides a method of preparing a titania nanotube membrane, the method including growing a plurality of titania nanotubes on a first side of a titanium substrate under anodizatton conditions, such that a first end of each nanotube is closed and attached to the titanium substrate and a second end of each nanotube is open. The method also includes etching the titanium substrate on the side opposite the first side, under conditions sufficient to open the first end of a first group of the titania nanotubes, thereby preparing the titama nanotube membrane.
  • the water present in the anodization solution can be present in any suitable amount.
  • water can be present in an amount such as 0.1 , 0.5 I, 2, 3, 4, 5, 10, 20, 30, 40 or 50 wt %.
  • the wafer is present in an amount of from about 0, 1 to about 50 wt %.
  • the water is present in an amount of from about 0.1 to about 5 wt %,
  • Each fabrication fixture and cathode insert are dried separately with nitrogen and placed in a clean screw-top container. Tweezers and secondary containment are rinsed with water and dried with nitrogen or allowed to air dry. The neutralized anodization solution is flushed in a sink with several liters of water (a faucet is left running for ⁇ 2-3 minutes).
