UV-VIS spectroscopic analysis of oligonucleotide DNA exposed to different magnetic fields was performed in order to investigate the relationship between DNA extinction coefficients and optical parameters according to magnetic-field strength. The results with the oligonucleotides adenine-thymine 100 mer (AT-100 DNA) and cytosine-guanine 100 mer (CG-100 DNA) indicate that the magnetic field influences DNA molar extinction coefficients and refractive indexes. The imaginary parts of the refractive index and molar extinction coefficients of the AT-100 and CG-100 DNA decreased after exposure to a magnetic field of 750 mT due to cleavage of the DNA oligonucleotides into smaller segments.
对暴露于不同磁场中的寡核苷酸 DNA 进行了 UV-VIS 光谱分析，以便根据磁场强度研究 DNA 消光系数与光学参数之间的关系。与腺嘌呤-胸腺嘧啶 100 mer（AT-100 DNA）和胞嘧啶-鸟嘌呤 100 mer（CG-100 DNA）的结果表明，磁场会影响 DNA 的摩尔消光系数和折射率。暴露于 750 mT 的磁场后，AT-100 和 CG-100 DNA 的折射率和摩尔消光系数的虚部减小，这是由于 DNA 寡核苷酸被切割成较小的片段。
