In this study, an alkanethiol-assisted self-assembly of Au nano-particles and its size tunable technique were confirmed. To fabricate a one-dimensional (1D) template, -DNA was first laid on mica substrate by dropping diluted -DNA solution, 12.6 ng/[micro sign]l, on freshly cleaved mica. By dropping colloidal gold solution on mica surface with the DNA templates laid on it, the -DNA was then pulled straight via capillary force by applying solvent absorbing tissue at outer circumference of the mica substrate. Moreover, it fixed on mica via gravity force and Van der Waals force between mica surface and the DNA. Au nano-particles would be arrayed along the straight DNA molecules to form 1D Au arrays. Then based on the synthesis of 1D nano-structure via DNA template and Au nano-particles, the simple 2D nano-structure, a ring, would also be studied.
本研究通过巯基乙酸辅助的自组装证实了金纳米粒子的自组装及其尺寸可调技术。为了制备一维（1D）模板，首先通过滴加稀释的- DNA 溶液（12.6ng/[micro sign]l）在新劈开的云母上放置 -DNA。通过将胶体金溶液滴加到带有 DNA 模板的云母表面上，通过在云母基底外周的吸收溶剂的组织施加毛细作用力将 -DNA 拉直。此外，它通过重力和云母表面与 DNA 之间的范德华力固定在云母上。金纳米粒子将沿着直线 DNA 分子排列，形成一维 Au 阵列。然后，基于 DNA 模板和 Au 纳米粒子合成的一维纳米结构，还研究了简单的二维纳米结构——一个环。
