摘要
A miniature controllable drug delivery device in which drug release is achieved by actuating polymeric valves is introduced. The valves made in flap configuration are bilayer structures which were fabricated as a thin gold film and an electrochemically deposited polypyrrole (PPy) layer. A drug simulate was stored in a reservoir and the drug release process was accomplished by bending the bilayer flaps with a small electrical potential bias in solution. The detailed fabrication procedures of this controllable drug delivery device are presented.
