DNA - Directed Synthesis of ZnO Nanowires

摘要

In this paper, a new and simple method for the synthesis of ZnO nanowires under very mild conditions is presented. The nanowire preparation is based on mineralization from alkaline aqueous zinc nitrate solution in the presence of fish sperm DNA as a structure-directing agent. The morphological features of the obtained structures were investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), while the structural characterization of ZnO was done by X-ray diffraction.
