Carbon nanomaterials as electrochemical sensors

Electrochemical sensors have been attracted widespread attention in detection due to their simple instruments, high sensitivity, fast response, and good selectivity. Carbon materials secure toprogress a plenty of real-world technologies. Carbon nanomaterials have shown great applicationpotential in electrochemical sensing technology due to their unique electrical, optical, thermal,mechanical and chemical properties [۱].Carbon nanomaterials and their nanocomposites demonstrates high electrochemical performance [۲]. Due to the high electrical conductivity, these materials could be utilized as ideal electrontransfer medium in numerous electrochemical systems [۳]. On the other hand, by possessing oflarge surface area and small pore dimension, carbon nanomaterials show high electrocatalytic andstorage performances [۴]. To improve their functions significantly in electrochemical activity,carbon nanomaterials could be easily functionalized with different moieties. Also, biocompatibility of the carbon nanomaterials facilitate their applications in biological fields.In this paper, technologies of electrochemical sensors based on carbon nanomaterials for detection purposes were introduced.
