Drug Delivery System

Figure 1 shows a cross-section of a prototype drug delivery system. The thin gold membrane is removed electrochemically to
release the drug located in the cavity. Figure 2 shows the electrode configuration with figure 3 showing a close up of the
electrodes in the 12 cavity prototype shown in figure 4.
