| 中文摘要 | in-situ fourier transform infra-red (ftir) spectra of native and thermally denatured calf thymus dna (ct dna) adsorbed and/or oxidized at a glassy carbon (gc) electrode surface are reported. the adsorption of native dna occurs throughout the potential range (-0.2 similar to 1.3 v) studied, and the adsorbing state of dna at electrode surface is changed from through the c=o band of bases and pyrimidine rings to through the c=o of cytosine and imidazole rings while the potential shifts negatively from 1.3 v to -0.2 v. an in-situ ftir spectrum of native ct dna adsorbed at gc electrode surface is similar to that of the dissolved dna, indicating that the structure of ct dna is not distorted while it is adsorbed at the gc electrode surface. in the potential range of -0.2 similar to 1.30 v, the temperature-denatured ct dna is adsorbed at the electrode surface first, then undergoes electrochemical oxidation reaction and following that, diffuses away from the electrode surface.
