Abstract

Electrical transport through DNA molecules is of fundamental interest and could have an impact on nanoscale device applications such as molecular electronics. A few interesting transport data have been reported in the last couple of years, but the transport mechanism through DNA molecules is less understood. We report direct measurements of electrical conduction through 60 base pairs of poly(G)-poly(C) DNA molecules (20.7 nm long) connected in between two metal electrodes with nanometer spacing.

聚(G)-聚(C) DNA分子的电输运性质

通过DNA分子的电传输是一个基本的兴趣，并可能对纳米级器件的应用产生影响，如分子电子学。在过去的几年里，已经报道了一些有趣的传输数据，但是通过DNA分子的传输机制却鲜为人知。我们报告了通过60个碱基对poly(G)-poly(C) DNA分子(20.7 nm长)连接在两个纳米间距的金属电极之间的电导率的直接测量。
