Abstract Glyphosate, a widely used herbicide, has raised significant environmental and health concerns due to its persistence in food matrices. Accurate sensitive detection methods are essential for monitoring glyphosate contamination ensuring safety. In this study, fluorescent probe (DSG‐Cu[II]) been developed the selective of glyphosate. The fluorophore making is synthesized through reaction between dansyl chloride glycine, forming (DSG) capable binding copper ions (Cu[II]). resulting DSG‐Cu[II] complex functions via an “off‐on” fluorescence mechanism, wherein competitively displaces Cu[II], restoring fluorescence. This approach demonstrates high sensitivity rapid response, with limit 35 nM response time 30 s. Furthermore, was successfully applied real sample analysis, confirming practical applicability. Additionally, test strips incorporating enabled visual detection, highlighting potential on‐site monitoring. study presents efficient, selective, fluorescence‐based method contributing improved safety
