美国麻省理工学院和哈佛大学的科学家,利用DNA构建出具有独特电子特性的石墨烯纳米结构,向大规模生产石墨烯电子芯片迈出了非常重要的一步。科学家通过控制DNA序列,操纵分子形成不同折叠形状的DNA纳米结构,以此为模板,进而可以控制无机材料的纳米结构,从而在一个碳原子厚的石墨烯片上形成不同的纳米级图案。这些DNA纳米结构是采用一种名为DNA单链片的方 Massachusetts Institute of Technology and Harvard University scientists, the use of DNA to construct a unique electronic properties of graphene nanostructures, to large-scale production of graphene electronic chip has taken a very important step. By controlling DNA sequences and manipulating molecules to form DNA nanostructures with different folding shapes, scientists can manipulate the nanostructures of inorganic materials to form different nanoscale patterns on a carbon-thick graphene sheet. These DNA nanostructures use a single-stranded piece of DNA
