Recent Advances in Non-Enzymatic Electrochemical Sensors for Glyphosate Detection: A Review

Résumé fourni par la source

Glyphosate (GLY) is the most widely used organophosphorus pesticides globally with application in shielding crops against perennial and annual the weeds, domestic garden and agriculture. It is recognized for its toxicological harm and is implicated in potential connections with human carcinogenesis. Generally, glyphosate is considered to be less toxic but excessive use leads to pollute soil, food and water. Furthermore, it strongly effects the unicellular and multicellular organism. Therefore, there is urgent need to develop specific, accurate, online, and sensitive methods for detection of glyphosate. The present review is focused on recent advances in developing non-enzymatic sensors for glyphosate detection. Non-enzymatic electrochemical sensors have emerged as promising alternatives for glyphosate detection, offering advantages such as high sensitivity, selectivity, and rapid response. The electrodes were modified with metals, carbon materials, metal organic framework and molecular imprinted polymers using various electrochemical techniques. Execution, benefits, linear range, detection limit and limitations of the modified sensors for determination of glyphosate are reviewed thoroughly.
