Abstract
Membranes useful for amperometric sensors are described. The membranes allow continuous and real time in vivo measurements of a variety of redox active chemical species present in a fluid sample. In some embodiments, the membrane comprises a redox mediator, a redox reactive species, and conductive nano structures, such as carbon nanotubes. The membrane can be provided on a working electrode of the sensor. Amperometric sensors incorporating the membranes and methods of treatment using the sensors are also described.
