| 中文摘要 | Spectroscopic and viscosity methods were applied to investigate the mechanism of interaction between Congo red (CR)-Sm(III) complex and herring sperm DNA by using acridine orange as a spectral probe in Tris-HCl buffer (pH 7.40). The binding ratio of Sm(III)(CR)3 : DNA is 5 : 1, the apparent molar absorptivity of epsilon Sm(III)(CR)3-DNA is 4.80 x 105 L (mol cm)-1 and the bonding constant of Sm(III)(CR)3 interacting with DNA is [image omitted] = 1.11 x 107 L mol-1. The thermodynamic parameters are r[image omitted] = 5.40 x 104 J mol-1, r[image omitted] = 3.16 x 102 J (mol K)-1, r[image omitted] = -4.03 x 104 J mol-1. The results confirm that the interaction between Sm(III)(CR)3 complex and DNA is a partial intercalation, and the reaction process is entropy favorable. |
