DNA模板调控纳米无机材料生长

Growth of Nano-inorganic Material Modulated by DNA Templates

以DNA为模板诱导纳米无机晶体的生长是近年来一个新的研究方向。DNA模板具有完善和严密的分子识别功能,使其组装过程具有高度的选择性。通过人为控制DNA的形状、长度和序列,可以制备出不同结构的纳米功能材料。本文讨论了DNA模板诱导硫化镉、四氧化三铁、硫酸钡、氯化镁和二氧化硅等纳米无机晶体的生长。

The growth of nano-inorganic crystals induced by DNA templates is a new research field. DNA templates have a perfect and exquisite ablility of molecular recognition. It is possible to make a nanofunctional material with different structures by controlling the shape, length and sequence of DNA. The growth of a series of nano-inorganic crystals induced by DNA templates is summarized in this paper. The nano-crystals include cadmium sulfide, iron oxide, barium sulphate, magnesium chloride, silica and so on.
