项目摘要
The purpose of this project is to prepare a DNA aligned film that shows a large anisotropic conductivity along DNA strands in the film. DNA is believed to be having an ability of electron transfer, because DNA has many π-electrons within the stacked base pairs. We prepared DNA-lipid films and measured their conductivities. In this research, we tried to measure the conductivity of a single DNA molecule as a nanowire. We have prepared DNA-nanowires by using Langmuir-Blodgett method, and observed aligned DNA -nanowires by a fluorescent microscopy. Further, the electron conductivity of DNA-nanowires was also measured on an interdigitated microcuit. We found that DNA-nanowires are good semiconductor (0.1-1S cm-1) from conductivity measurements.
本项目的目的是制备一种DNA取向膜,该膜沿膜中的DNA链显示出大的各向异性导电性。DNA被认为具有电子转移的能力,因为DNA在堆叠的碱基对内具有许多π电子。我们制备了DNA-脂质膜,并测量了它们的电导率。在这项研究中,我们试图测量单个DNA分子作为纳米线的电导率。我们用Langmuir-Blodgett方法制备了DNA纳米线,并用荧光显微镜观察了DNA纳米线的排列。此外,DNA纳米线的电子电导率也在叉指型微探针上测量。通过电导率测量,我们发现DNA纳米线是良好的半导体(0.1- 1 S cm-1)。
