金属介导的DNA双链体（金属-DNA）的电学性质由于其在基于DNA的纳米电子学中的潜在应用而受到特别关注。我们制备了HgII介导的带有NH 2锚的DNA双链体，并在缓冲溶液中用基于扫描隧道显微镜的断裂连接法测量了单分子金属-DNA的电导。观察到三个电导值，可能对应于不同的构象的金属-DNA分子桥接在金属电极。
Electrical properties of metal-mediated DNA duplexes (metallo-DNA) have been of particular interest because of their potential applications in DNA-based nanoelectronics. We prepared HgII-mediated DNA duplex with NH2anchors and measured the electrical conductance of single-molecule metallo-DNA via scanning tunneling microscopy-based break junction method in the buffered solution. Three conductance values were observed that may correspond to different conformations of the metallo-DNA molecule bridged over metallic electrodes.
