Electrochemical Sensors for Enhanced and Rapid Detection of Illicit Drugs

The consumption of illicit drugs is spread worldwide and remains a challenge for concerned authorities. Hence, it is vital to develop effective and precise methods for detecting these types of compounds in biological fluids, seized street samples, and wastewaters. Electrochemical sensors are extensively used for analysis in many fields and represent an exclusive prospect to permit inexpensive, fast, and accurate monitoring and detection simultaneously. Electrochemical approaches are mainly open to forensic investigation because of their high performance in turbid and complex matrices. In this minireview, recent electrochemical strategies applied to the detection of illicit drugs in different samples have been presented.
