Figure 6

Fluorescence titration (a) Change in emission intensity of C1 with the addition of an increasing amount of fluoride (0.1–47 μM), (b) Change in emission intensity of C2 with the addition of an increasing amount of arsenate (5–500 nM), (c) Stern–Volmer plot for fluoride, Inset: LOD, (d) Stern–Volmer plot for arsenate, Inset: LOD; Change in color of C1 (e) and C2 (f) upon incremental addition of fluoride and arsenate respectively (top), the addition of an equal proportion of methylene blue dye onto each solution (bottom).
