(A) Time-resolved fluorescence anisotropy decays of Cy3-labeled DNA origami. The anisotropy decays of the single labeled constructs, G1, G2 and G3 (orange, purple and green line, respectively) show similar behavior while the decay of the triple-labeled construct (G1G2G3, blue line) shows decreased anisotropy confirming homo-FRET occurrence. (B) Fluorescence lifetimes of the same constructs. The lifetime decay of G1G2G3R (blue) shows a reduction in lifetime compared to that of the single-labeled constructs.
