质粒DNA的拓扑结构不同，经两个阳离子交换步骤处理后，以DNA为模板，溶胶-凝胶缩聚四乙氧基硅烷，可成功转录成二氧化硅结构（见方案）。这些发现表明，同一模板通过其高阶构象变化可以形成不同的有序二氧化硅结构。
The topologically different structures in plasmid DNA can be successfully transcribed into silica structures by using the DNA as a template for sol-gel polycondensation of tetraethoxysilane after treatment by two cation-exchange steps (see scheme). These findings imply that the different ordered silica structures can be created from the same template through its higher-order conformational changes.
