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.

Keywords:

Carbon nanotubes, electrochemical sensors, drug analysis, food analysis, nanomaterials, review.
