Under the skin drug delivery

A US company called MicroChips is currently testing an implantable drug-delivery system. From the Technology Review article, “About the size of an Oreo cookie, the device used in the test consists of a silicon and glass microchip that contains 100 miniature drug reservoirs, each about 50 micrometers wide at the top, plus a battery and electronics controlling drug release, sealed in a titanium case.” A perfect application for this device would be diabetics (or others) who need regular injections; we may actually see human trials within 5 years.
