The peptide nano-rings containing Au nanoparticles inside their cavities were self-assembled on dithiol SAMs patterned as an array by AFM-based nanolithography. The peptide nano-rings were aligned as a line on these SAMs, and Au formed lines with the spacing between these nanoparticles as the peptide nano-rings functioned as spacers. This type of array fabrication will provide improved tunability in their optical properties of resulting nanoparticle-assembled arrays. In addition, optimization of the inter-particle distance of nanoparticles in the array with various spacers may allow one to design new types of photonic crystals with desired optical properties.

含金纳米粒子肽纳米环在表面的自组装

腔内含有金纳米颗粒的肽纳米环在二硫醇 SAM 上自组装，通过基于 AFM 的纳米光刻技术将其图案化为阵列。肽纳米环在这些 SAM 上排列成一条线，Au 与这些纳米颗粒之间的间距形成线，因为肽纳米环充当间隔物。这种类型的阵列制造将在所得纳米颗粒组装阵列的光学特性方面提供改进的可调性。此外，通过各种间隔物优化阵列中纳米粒子的粒子间距离，可以设计出具有所需光学特性的新型光子晶体。
