The appearance of this band can be attributed to the formatio n of the thionine dimers (H-type), consistent with similar spectr al changes observed for thionine in the presence of gold nanoparticles [37]. The analysis of data presented in Fig. 6 shows that the normalized absorption intensity of the band at λmax4 increases with the concentration up to 7.5 mg/L and then reach es a plateau. We believe that this growth is caused by the thionine intercalation between nucleobases, which ends a t 7.5 mg/L.
