英文摘要	研究了核苷酸、聚核苷酸和核酸对Tb3+-钛铁试剂（Tr）络合物的荧光碎灭机理，认为荧光猝灭过程是核苷酸、聚核苷酸和核酸分子中的磷酸基组分与Tr竞争Tb3+离子，生成实验条件下无荧光的二元络合物的静态猝灭过程；用Tb3+-Tr络合物荧光探针研究dnA嵌入剂和金属离子与dnA相互作用的实验结果说明这一机理是合理的.; The mechanism of Fluorescence quenching of Tb3+-Trion complex by nucleotides,polynucleotides and nucleic acids has been studied.It was considered that it is a static quenching which is based on the phosphate moieties of nucleotides, polynucleotides and nucleic acids conpeting the Tb3+ ion with Tiron and Forming non-Fluorescent binary complex under the optimal conditions.The experimental results of nucleic acids reacting with intercalating reagent of DNA or metal ion using Tb3+-Trion complex as a Fluorescence probe indicated that the mechanism is reasonable.; 国家教育委员会博士点基金
