All experimental results indicate that the complex binds to DNA by the electrostatic mode and the groove binding mode. Information such as intrinsic binding costant ( k = 1. 426 × 104 mol·L^-1 ), and binding numbers ( n = 2), were determined by cyclic vohammetry and differential pulse vohammetry at glass carbon electrode. Interaction between Eu^3+ with rutin was also studied by UV-visible spectroscopy.展开更多

The stoichiometry of the complexes and their formation constants have been estimated. The thermodynamic parameters for the formation of complexes were obtained. The complexing ability of HP-beta-CD is remarkably stronger than beta-CD and gamma-CD.展开更多
