Functionalization of Carbon Nanotubes for Bioelectrochemical Applications

Abstract

Due to the increasing need to monitor health and environment in real time and to energize small electronic devices, new materials are under extensive investigations. Between others, carbon nanotubes (CNTs) are promising alternatives as building blocks in bioelectrochemical devices due to their unique electrical, mechanical properties, and their high specific surface. Furthermore, their ease and well-established organic functionalization brings new properties to nanostructured electrodes such as specific docking sites for biomolecules. Moreover, CNT films exhibit a high electroactive surface area due to the natural formation of highly porous three-dimensional networks, suitable for the anchoring of a high amount of bioreceptor units, thus leading to improved sensitivities. With some simple functionalization techniques, CNTs can acts as almost perfect support for enzyme wiring and is still the privileged material in the field of enzymatic biofuel cells. The most appropriate functionalization techniques for CNTs are summarized leading to enhance the performances of biosensors and biofuel cells.
