由超薄纳米片组成的氢氧化铜三维树枝状纳米结构，在铜金属自然氧化静态提供的无杂质营养物质的近乎持续过饱和的条件下逐步合成。相邻的树突纳米结构可以进一步扩展，并最终通过反应-体积控制的生长在甲酰胺水溶液中自组织/合并成令人印象深刻的双连续网络。当最简单的氨基酸甘氨酸作为有机添加剂时，可以相应地制备出高阶的、壳状装饰的树枝状纳米结构。研究表明，更复杂的纳米结构材料可以在几乎持续的过饱和条件下化学合成，并在生物分子作为模板时进一步修饰。
Complex 3D dendritic nanoarchitectures of copper hydroxide built up of ultrathin nanosheets have been synthesized progressively under nearly sustained supersaturation of impurity-free nutrients that are supplied statically from the natural oxidation of copper metal. Adjacent dendritic nanoarchitectures can further expand and eventually self-organize/merge themselves into impressive bicontinuous networks through the reaction-volume-controlled growth in formamide aqueous solution. When the simplest amino acid, glycine, was used as organic additive, high-order, shell-ornamented dendritic nanoarchitectures can be fabricated accordingly. A clear perspective is shown here that more complex nanostructured materials could be chemically synthesized under nearly sustained supersaturation and further decorated when biological molecules are used as templates.
