摘要：
The interaction of [Ru(2, 2'-bipyridine)2(2-benzo[b] thien-2-yl-1H-imidazo[4,5-f][1,10] phen-anthroline)](2+) ([Ru(bpy)(2)(BTIP)](2+)) with nucleic acids in weak acidic medium is studied based upon the measurements of resonance light scattering (RLS) and UV-vis absorbance. Intercalation, electrostatic interaction, and long-range assembly are observed between [Ru(bpy)(2)(BTIP)](2+) and calf-thymus DNA (ctDNA). The enhanced RLS intensity is proportional to the concentration of ctDNA in an appropriate range. Three synthetic samples are analyzed satisfactorily.
