英文摘要The action mode between Dy(III)(NR)(3) and herring sperm DNA is studied by ultraviolet-visible (UV-vis) and fluorescence spectra as well as electrochemistry. Double-reciprocal method studies show that the binding stoichiometry between Dy(III)(NR)(3) and DNA is 1 : 1, the binding constants at different temperatures are 1.15 x 10(5) L/mol at 25 degrees C and 2.09 x 10(5) L/mol at 35 degrees C, and the corresponding thermodynamic parameters are Delta H-r(m)Theta = 2.48 x 10(4) J/mol, Delta(r)G(m)(Theta) = -2.34 x 10(4) J/mol, Delta S-r(m)Theta = 161.7 J/(mol . K), Delta S-r(m)Theta is the driving force in this reaction. Combined with Scatchard method and melting method, the results suggest that, the interaction mode between Dy(III)(NR)(3) and herring sperm DNA is intercalation fashion and groove fashion.
