After binding with tRNA, TH/MB dyes displayed emission, and absorption characteristics were significantly changed. The observed tRNA-induced spectral alterations are attributed to energy transfer from guanine base pairs, likely resulting from an intercalative interaction mode proposed for tRNA. The negative free energy change value (ΔG = ~ − 27.5 kJ mol−1) of the TH/MB dye–tRNA systems suggests that the present binding interaction is highly favorable and spontaneous. The conformational alterations of the tRNA with both dyes were verified using circular dichroism analyses.
