纳米颗粒具有独特的、与尺寸相关的性质，这些性质与磁性、光子学、化学和电学行为相关，这些性质与它们各自的块体材料中的性质不同。这些性质可以通过将纳米颗粒固定在适当的基底上来控制。因此，在固体基底上构建纳米粒子的有序结构是非常必要的。我们成功地将银（Ag）纳米粒子在水溶性二硫醇自组装单分子层（SAM）纳米粒子上进行了可控阵列，如线、空间和点。球形银纳米粒子排列在金纳米粒子上，间隙距离为几纳米，由水溶性二硫醇支撑。两种二硫醇自组装膜的银纳米粒子的附着行为的差异被清楚地观察到。
Nanoparticles have unique, size-dependent properties associated with magnetic, photonic, chemical, and electrical behavior, which are different from the properties in their respective bulk materials. Those properties can be controlled through the immobilization of nanoparticles on an appropriate substrate. Therefore, it is essential to construct ordered structure of the nanoparticles on solid substrate. We succeeded in the the controlled array of silver (Ag) nanoparticles on the resulting water-soluble dithiol self-assembled monolayer (SAM) nanopatterns such as line and space and dots. Spherical Ag nanopartcles were arrayed above gold nanopatterns with a gap distance of a few nanometers supported by water-soluble dithiol. The difference in attachment behavior of Ag nanoparticle between two kinds of dithiol SAMs was clearly observed.
