Enzymatic and non-enzymatic detectors and associated membrane apparatus, and methods of use, such as within a fully implantable sensor apparatus. In one embodiment, detector performance is controlled through selective use of membrane configurations and enzyme region shapes, which enable accurate detection of blood glucose level within the solid tissue of the living host for extended periods of time. Isolation between the host's tissue and the underlying enzymes and reaction byproducts used in the detectors is also advantageously maintained in one embodiment via use of a non-enzyme containing permeable membrane formed of e.g., a biocompatible crosslinked protein-based material. Control of response range and/or rate in some embodiments also permits customization of sensor elements. In one variant, heterogeneous detector elements are used to, e.g., accommodate a wider range of blood glucose concentration within the host. Methods of manufacturing the membranes and detectors, including methods to increase reliability, are also disclosed.
