An implantable, microchip-based device may soon replace the injections and pills now needed to treat chronic diseases: Earlier this month, MIT spinout Microchips Biotech partnered with a pharmaceutical giant to commercialize its wirelessly controlled, implantable, microchip-based devices that store and release drugs inside the body over many years. Invented by Microchips Biotech co-founders Michael Cima, the David H. Koch Professor of Engineering, and Robert Langer, the David H. Koch Institute Professor, the microchips consist of hundreds of pinhead-sized reservoirs, each capped with a metal membrane, that store tiny doses of therapeutics or chemicals.
