Figure 9. Emission spectrum of the 2/duplex system ([2] = 1 µM, [dsDNA] = 0.25 µM) in the presence of increasing concentrations of ATP (0, 2.5, 10, 50, 100, 500, 1000, 2500 and 5000 µM). λ_ex = 360 nm (left).

Luminescence response of the system vs. log [ATP]. Inset: linear plot of the change in luminescence intensity of the system vs. ATP concentration (right).
