The development of facile techniques for precisely patterning complex metal and metal oxide nanostructures is essential for catalytic nanosystems, and optical and electronical nanodevices. Herein, we report a general strate-gy for designing and fabricating metal and metal oxide nanoclusters (MMONs) with arbitrarily prescribed patterns on DNA origami templates. The valuable feature of our ap-proach lies in the site-specific arrangement of thiol groups on DNA origami, which act as reaction centers, initiating in situ MMONs growth. This strategy can be generalized to the patterning of arbitrary geometries and various inorganic materials, which will aid the generation of complex and precisely-arranged components for customized functional nanoarchitectures.

在 DNA 折纸上将金属和金属氧化物纳米团簇精确组织成任意图案

用于精确图案化复杂金属和金属氧化物纳米结构的简便技术的发展对于催化纳米系统以及光学和电子纳米器件至关重要。在此，我们报告了在 DNA 折纸模板上设计和制造具有任意规定图案的金属和金属氧化物纳米团簇 (MMON) 的一般策略。我们的方法的有价值的特征在于 DNA 折纸上硫醇基团的位点特异性排列，它们充当反应中心，启动原位 MMON 生长。这种策略可以推广到任意几何形状和各种无机材料的图案化，这将有助于为定制的功能纳米结构生成复杂且精确排列的组件。
