| 摘 要： | 随着DNA金属化工艺逐渐发展, 以DNA为模板进行金属纳米线的制备, 使得生物与微细加工技术的结合变得可能. 我们将DNA模板金属化工艺加以改进, 利用半导体材料——硅作为样品衬底, 并在硅片上利用Parafilm疏水膜斜向拉伸排列DNA分子, 采用化学还原反应, 成功地进行了银纳米线的制备. 改进后的金属化工艺对DNA分子金属化程度较好, 而且制备出了金属纳米网状结构. 基于DNA构筑复杂纳米图形的实现, 进行相关的金属化, 有望构筑纳米集成电路.

| Abstract: | Metallization processes of DNA have been developing quickly, and DNA-templated construction of nanowires provides a possibility of the combination of biology and micro/nano fabrication. In this article, the traditional DNA elongating and metallization process was improved by the use of semiconductor material—silicon as the sample substrate. The good linear DNA was achieved by tilted elongation method. The novel metallization process proves to be a good method for fabrication of metal nanowires and nano networks on DNA. With the accomplishment of difficult nano-patterns by DNA construction, sequential metallization can be carried out and nano integrate circuits constructed in the future. |
