“…A large number of sensitive protocols have been reported for sulde detection. These methods include classical titrimetry, 16 electrochemical techniques, [17][18][19] spectrophotometry, [20][21][22] chemiluminescence, 23 chromatography, [24][25][26] and uorimetry. [27][28][29][30][31] Among these methods, uorescence detection methods offer a promising opportunity due to the unique advantages of rapidity, sensitivity, convenience, simplicity, easy operation, and low cost.…”
