Minireview - Recent Developments in Electrochemical Detection of Atrazine

Atrazine is a common triazine herbicide that is persistent in the environment due to its water solubility and slow degradation. Some of the effects of atrazine exposure include immune suppression, carcinogenicity, hormone disruptions, and reproductive anomalies; thus its determination is of great importance. This minireview provides a summary of the most recent developments in electrochemical sensors that target atrazine by using nanoscale materials as electrode modifiers, such as metal/metal oxide nanoparticles, carbonaceous materials, and conducting polymers. Analytical parameters such as the linear dynamic range, detection limit, and detection method, are compiled and compared with the experimental conditions. Lastly, the future directions, difficulties, and opportunities for developing new sensing technology are presented.
