Abstract:
Background: Electrochemical sensors are widely used for the determination of drugs and
food compounds. In recent years, the amplification of electrochemical signals with nanomaterials, especially
Carbon Nanotubes (CNTs) has created a major revolution in electrochemistry.
Objective: The present mini-review paper focused on studying the role of CNTs as conductive mediators
for the fabrication of highly sensitive electrochemical sensors. CNTs, with high conductivity and
good ability for modification with other materials, are interesting candidates for improving the sensitivity
of electrochemical sensors. CNTs or their derivatives are suggested for different applications in
electrochemistry and especially analytical biosensors. This review is aimed to discuss the conductivity
feature of CNTs in electrochemical sensors.
