Resumen:
The goal of this chapter is to summarize the recent advances in carbon
nanotubes as a new material for electrochemical sensors. Since their discovery in
1991, carbon nanotubes have received considerable attention in different fields.
Their special geometry and unique electronic, mechanical, chemical and thermal
properties make them a very attractive material for the design of electrochemical
biosensors.
The first application of carbon nanotubes in the preparation of a sensor was
reported by Britto in 1996. Since then, an increasing number of publications
involving sensors based on carbon nanotubes (either single or multi-wall) for
substrates like glucose, lactate, alcohols, phenols, neurotransmitters, aminoacids,
proteins, carbohydrates among others, have been reported. This fact demonstrates
the usefulness of carbon nanotubes for the development of electrochemical
sensors.
The advantages of carbon nanotubes for promoting electron transfer reactions
-with special emphasis in those involving biomolecules-, the different
methodologies for incorporating carbon nanotubes in sensors (either suspended in
solutions, in polymeric films or in composite matrices), the analytical performance
of the resulting biosensors as well as future prospects are discussed in this article.
