“…The studied drugs were previously analyzed utilizing various analytical techniques, including HPLC (High-Performance Liquid Chromatography), [21][22][23][24][25] spectrophotometric, 26,27 spectrouorometric, [28][29][30][31][32][33][34] and electrochemical methods. [35][36][37][38][39] Fluorescent metal nanoclusters are emerging as a new class of nanoscale uorophores. 40 Metal nanoclusters with particle sizes below 10 nm exhibit bright photoluminescence emission due to quantum connement effects.…”
