手性结构在化学、生物学、数学和物理学等许多研究领域都展现出了一些不可避免且迷人的特性。在本文中，我们报道了利用逐步掠角沉积技术来制备三维手性纳米结构。通过优化沉积参数（例如聚苯乙烯球（PS）阵列的取向角、沉积角度、厚度和数量），已经获得了大量的手性结构，并且它们的尺寸取决于PS球的直径。这些手性结构都可以通过使用三维几何模型进行模拟和预先设计，这极大地提高了该方法的效率。此外，圆二色性光谱表明这些手性结构具有明显的科顿效应，这表明它们作为三维手性超材料具有潜在的应用。
The chiral structures have displayed some inevitable and fascinating properties in many research fields, such as chemistry, biology, mathematics, and physics. In this Article, we report the use of stepwise glancing angle deposition technology to produce the 3D chiral nanostructures. Through the optimization of deposition parameters (such as the orientation angle of poly styrene spheres (PSs) array, the deposition angle, thickness, and number), a great number of chiral structures have been achieved, and their size depends on the diameter of PS spheres. These chiral structures all can be simulated and predesigned through the use of a 3D geometrical model, which greatly improves the efficiency of this method. In addition, the circular dichroism spectrum shows that these chiral structures own an obvious Cotton effect, indicating their potential application as 3D chiral metamaterials.
