Recently, carbon nanotubes (CNT) and graphene have been chosen as
electrode material due to their unique mechanical, optical and electrical properties.
These carbon-based materials are used to facilitate electrode reaction and produce an
electrocatalytic effect. Moreover, a plethora of literature has emerged concerning CNT
and graphene being employed to obtain a more selective and sensitive analysis. This
chapter reviews this emerging literature focusing on drug analysis from pharmaceutical
dosage forms and biological matrices. To achieve this, first, there is a summary of the
basic properties, synthesis, characterization, electrode preparation and
advantages/limitations of these materials, and then a selection of the literature from
2010 to 2017 is presented, which summarizes the type of electrode, electrochemical
techniques, peak potential of drug compounds and the limit of detection values.
