A highly selective fluorescent probe for gold ion detection

In this issue, we introduce a new fluorescent probe for the detection of Au3 +. The probe is derived from 4,5-fluorescein trioxane, which shows high selectivity and sensitivity to gold ions in aqueous solution. There is a good linear relationship between the fluorescence intensity at 523 nm and the concentration of Au3 + in the […]
