We present results from high-resolution electron energy loss spectroscopy (HREELS) and XPS studies of self-assembled monolayers of DNA. The monolayers are well-organized and display sharp vibrational peaks in the HREEL spectra. The electrons interact mainly with the backbone of the DNA. The XPS results indicate that, in most of the samples studied, the phosphates on the DNA are not charged.
我们展示了对DNA自组装单分子层进行高分辨率电子能量损失谱（HREELS）和X射线光电子能谱（XPS）研究的结果。这些单分子层排列有序，在HREEL光谱中显示出尖锐的振动峰。电子主要与DNA的主链相互作用。XPS结果表明，在大多数所研究的样品中，DNA上的磷酸盐不带电。
