a) Absorption spectra of ICR-191 (broken line) and mixtures of ICR and DNA (solid lines), ICR was at 10 µM, while DNA concentration varied from 1 to 60 µMbp, from top to bottom; l=3 cm; b) respective differential spectra; c) absorption spectra of ICR, free in solution (dotted line), and in complex with DNA (solid line).
