The last developments of sensors and biosensors involving microelectrodes modified with carbon nanotubes to detect species with biochemical or biological relevance are reviewed in this chapter. Apart from the different electrode configurations employed, special consideration is given to monitoring of neurotransmitters and the nitric oxide radical. The use of implantable microsensors for glucose detection in cells or tissues, the direct electrochemistry of proteins and some few examples of immunosensors and DNA sensors making use of this kind of modified microelectrodes are also treated. Finally we consider the future perspectives in this field.
