一维（1D）到三维（3D）的金属纳米颗粒的纳米尺度组装体可以表现出在非晶态中未观察到的新颖现象。自底向上组装技术有望克服自顶向下方法的分辨率限制，为纳米纤维领域带来新的希望。DNA折纸主要用于构建离散和可寻址的纳米结构，可用于将功能性胶体纳米颗粒组装成具有有趣性质的精细几何形状。本文综述了以DNA折纸结构为模板，对金纳米球、金纳米棒和银纳米颗粒等金属纳米颗粒进行精确组装的方法。最后讨论了其应用前景。
Nanoscale assemblies of metal nanoparticles in one dimension (1D) to three dimensions (3D) can exhibit novel phenomena that are not observed in the amorphous state. Bottom-up assembly technique is expected to overcome the resolution limit of top-down method and casts a new light on the nanofabrication field. DNA origami, which is mainly used to construct discrete and addressable nanostructures, can be utilized to assemble functional colloidal nanoparticles into delicate geometries with interesting properties. This review aims to summarize the methods that use DNA origami structures as templates to precisely organize metal nanoparticles, such as gold nanospheres (AuNSs) gold nanorods (AuNRs) and silver nanoparticles (AgNPs). The potential applications and the perspective are also discussed.
