The Rationale for Implantable Semi-Permeable Materials

The development of microchip-based bioassays and the proliferation of soluble markers of disease processes, such as cancer, suggests that implantable sensors will eventually be used to detect diseases very early in their course. The low concentrations of markers early in disease, and
