AI Article Synopsis
- - The study highlights the environmental and health risks associated with glyphosate usage and introduces a new detection method using ionic liquids to create a fluorescent probe (PDHN-Cu) for rapid detection.
- - Glyphosate's stronger binding to copper disrupts the PDHN-Cu structure, leading to a "turn-on" fluorescence that signals its presence, allowing detection in just one minute.
- - This innovative technique offers high sensitivity (detection limit of 71.4 nM) and recovery rates (97-103%) across different samples, paving the way for better monitoring of pesticides using competitive coordination principles.
Article Abstract
The widespread use of glyphosate (Gly) poses significant risks to environmental and human health, underscoring the urgent need for its sensitive and rapid detection. In this work, we innovated by developing a novel material, ionic liquids, which formed the ionic probe "[P][2,3-DHN]-Cu (PDHN-Cu)" through coordination with Cu. This probe capitalized on the distinctive fluorescence quenching properties of ionic liquids in the presence of Cu, driven by synergistic interactions between anions and cations. Glyphosate disrupted the PDHN-Cu coordination structure due to its stronger affinity for Cu, triggering a "turn-on" fluorescence response. Impressively, PDHN-Cu enabled the sensitive detection of glyphosate within just one minute, achieving a detection limit as low as 71.4 nM and excellent recovery rates of 97-103% in diverse samples. This groundbreaking approach, utilizing ionic probes, lays a robust foundation for the accurate and real-time monitoring of pesticides, employing a strategy based on synergism and competitive coordination.
