In this work, fluorescence resonance energy transfer (FRET) between tartrazine and 3-mercapto-1,2,4-triazole-capped gold nanoclusters (TRO-AuNCs) was investigated and subsequently utilized for the determination of tartrazine (TZ) in foodstuff samples. The TRO-AuNCs which exhibit strong fluorescence emission were synthesized by a simple one-pot procedure. Upon addition of TZ, the fluorescence of TRO-AuNCs...
