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.
