ABSTRACT
Nanomaterials and nanotechnology approaches to modifying surfaces promise to deliver the next gener-
ation of biosensors and bioelectronic devices for biomedical applications that will have improved per-
formance over existing technologies [1]. One of the opportunities that nanomaterials will provide is a more
efficient way of communicating the activity of biological molecules used in biosensors to the outside world
(that is the end user)[2]. Typically, this communication is achieved via the transfer of electrons, and in the
case of many devices, electrons must be transferred between redox protein and an electrode over which the
proteins are immobilized. This chapter will outline the approach employed by us [3-6] and others [7-11] to
improve this communication between redox proteins and electrodes using carbon nanotubes.
