Fluorescence decay fitting parameters (τ₁ and τ₂) of 5 µM SG in the absence and presence of 5 µM DNAs^Δ.

Δ<p>The lifetimes were measured at 415 nm (a) and 586 nm (b) with excitation at 336 nm. The lifetime measurement was not applicable for DNA3-Ys and DNA4-Ys due to the strong fluorescence quenching.
