(a) Schematic illustration of the poly-G-quadruplexes conjugated probe system. (b) Fluorescence emission spectra of ThT in the presence of TdT generated poly-G-quadruplexes. (c) Fluorescence emission spectra of the poly-G-quadruplexes-ThT upon addition of the TMPyP4. (d) UV-Vis absorption titration spectra of TMPyP4 with the poly-G-quadruplexes.
