Surfactant Modified Composite Electrodes for Electrochemical Determination of Drugs

Surfactants are surface-active agents, especially when it is combined with nanosensors; they may have an essential role in increasing the efficiency of the composite electrode, which will be analyzed by one of the electrochemical methods such as cyclic voltammetry, differential pulse voltammetry, and other techniques. The use of surfactant-modified composite electrodes shows considerable promise for drugs detection electrochemically in complicated matrices. Future research in this area has the ability to lead to the improvement of more sensitive, selective, and robust electrochemical sensors for drug analysis. In this chapter, some of the methods used for detecting and analyzing drugs using surfactant-based nanosensors are discussed, and the integration of surfactants and electrochemical nanosensors has opened up several roads for drug determination and analysis.
