A Novel and Sensitive Fluorescent Probe for Glyphosate Detection Based on Cu²⁺ Modulated Polydihydroxyphenylalanine Nanoparticles.

ABSTRACT: A novel and sensitive fluorescent probe based on Cu²⁺-modulated polydihydroxyphenylalanine nanoparticles (PDOAs) has been developed for the detection of glyphosate pesticides. Compared to conventional instrumental analysis techniques, fluorometric methods have obtained good results in the field of agricultural residue detection. However, most of the fluorescent chemosensors reported still have some limitations, such as long response times, the high limit of detection, and complex synthetic procedures. In this paper, a novel and sensitive fluorescent probe based on Cu²⁺ modulated polydihydroxyphenylalanine nanoparticles (PDOAs) has been developed for the detection of glyphosate pesticides. The fluorescence of PDOAs can be effectively quenched by Cu²⁺ through
