Glyphosate Detection: An Innovative Approach by Using Chemoresistive Gas Sensors

Glyphosate is the most frequently used herbicide worldwide, its hazard potential is unclear and nowadays a threshold limit value has not yet been determined. We used eight chemoresistive gas sensors based on semiconducting nanopowders for the identification of <i>N</i>-(phosphonomethyl)...
