摘要
无机纳米材料在一定维度上的精确功能化是纳米技术领域关注的焦点。我们利用DNA纳米折纸结构构建一个精确的表面图案化加工机器。通过巧妙的设计,无机纳米材料(纳米金粒子)可以精确的连接到DNA纳米折纸结构表面,通过启动DNA置换反应将DNA纳米折纸结构上的图案压印刻蚀到无机纳米材料表面。这些图案由DNA单链组成的,因此通过连接不同尺寸的纳米金粒子,实现了对高精度的纳米金团簇组装体在"原子价态"及角度方面的有效控制。手性金纳米金团簇的圆二色谱研究表明,该DNA折纸术的纳米压印光刻策略可以用于组装具有特定光学性质的无机纳米材料。
Precise functionalization of self-assembled nanostructures with spatial- and stereo- control represents a major concern in nanotechnology and holds great promise in various areas. Here, we exploited the nanoscale addressability of DNA origami to develop a precise copy machine-like platform. It can replicate on-origami two dimensional oligonucleotide patterns onto the surface of gold nanoparticles(Au NPs) via a deliberately designed toehold-initiated DNA displacement reaction. This DNA origami-based nanoimprinting lithography(DONIL) strategy exhibits high precision in controlling the valence and valence angle of Au NPs reminiscent of atoms. Thus-obtained DNA-decorated Au NPs act as precursors to construct discrete Au NPs clusters with desired chirality.
