螺旋结构以其独特的拓扑结构在过去的十年中引起了人们的广泛关注。旋转对称性，手性和不寻常的机械性能只是与螺旋几何相关的一些属性，使其在材料科学中具有特殊性。典型的螺旋几何学是生物系统的领域，在过去提供了它们结构多样性的惊人例子。如今，有效的合成策略允许生产各种无机螺旋结构，并且纳米技术的最新发展提供了在不同尺度上控制螺旋结构的额外可能性，实际上甚至比生物学中看到的更大的多样性。了解什么样的螺旋无机纳米材料是可用的，为什么不同种类的无机螺旋存在的两个基本主题，这篇评论。调查这些信息揭示了使用新螺旋结构的材料的可能性，并为其制备提供了一般原则。还指出了它们的合成方法、结构特征和性质的必要改进和进一步发展。
Helical structures with their unique topology have attracted broad attention during the past decade. Rotational symmetry, chirality, and unusual mechanical properties are just a few attributes associated with helical geometry that make it special for materials science. Typically helical geometry was the domain of biological systems which provided in the past amazing examples of their structural diversity. Nowadays, the effective synthesis strategy allows the production of various inorganic helical structures and the recent development of nanotechnology provides additional possibilities to control helical structures at different scales reaching, in fact even greater diversity than those seen in biology. Understanding what kind of helical inorganic nanoscale materials are available and why different kinds of inorganic helices exist are the two fundamental topics of this review. Surveying this information sheds light on the possibilities for materials using new helical structures and provides general principles for their preparation. Necessary improvements and further developments of their synthetic protocols, structural features, and properties are also indicated.
