Investigating and improving the performance of electrochemical sensors based on single-walled and multi-walled carbon nanotubes

In this research, the main focus is on the development of electrochemical sensors based on carbon nanotubes (CNTs). Carbon nanotubes are attractive new materials. About a decade has passed since the discovery of carbon nanotubes. Carbon nanotubes have many outstanding properties and have many practical or potential applications. Carbon nanotubes have unique electronic properties combined with chemical stability and behave electrically as a metal or semiconductor depending on their structure. The main rules of structure, energy parameters and sensor properties of modified semiconductor systems based on cable nanotubes by analyzing the mechanisms of interaction ofnanotubes with functional groups, metal nanoparticles and polymers that lead to the formation of chemically active sensors. The possibility of using boundary modified nanotubes to detect metals. It has been discussed. For sensing applications, carbon nanotubes have many advantages such as small size with larger surface area, excellent electron transport ability when used as electrode modifiers in electrochemical reactions. Carbon nanotubes play an important role in the performance ofelectrochemical biosensors, immunosensors and DNA biosensors. Various methods for designing sensors using CNTs have been developed in recent years. Here, we summarize the applications of CNTs in the fabrication of electrochemical sensors and biosensors along with conductive polymers.
