Abstract Pesticides in environmental samples pose significant risks to ecosystems and human health since they require precise efficient detection methods. Imidacloprid (IMI), a widely used neonicotinoid insecticide, exemplifies these hazards due its potential toxicity. This study addresses the urgent need for improved monitoring of such contaminants by introducing novel fluorometric method detecting IMI using nitrogen‐doped graphite carbon dots (N‐GCDs). The sensor operates quenching fluorescence through interaction Cu 2+ ions with N‐GCDs. Subsequently, binds imidazole group, chelates , restores alternating behavior allows accurate identification both IMI. exhibits linear ranges 20–100 nM 10–140 μg/L IMI, limits 18 1.2 μg/L, respectively. high sensitivity this enables real‐world samples, which underscores practical use agricultural safety.
