We disclose a method for the synthesis of chiral colloids from spontaneously formed hollow sugar-surfactant microtubes with internally confined mobile colloidal spheres. Key feature of our approach is the grafting of colloid surfaces with photoresponsive coumarin moieties, which allow for UV-induced, covalent clicking of colloids into permanent chains, with morphologies set by the colloid-to-tube diameter ratio. Subsequent dissolution of tube confinement yields aqueous suspensions that comprise bulk quantities of a variety of linear chains, including single helical chains of polystyrene colloids. These colloidal equivalents of chiral (DNA) molecules are intended for microscopic study of chiral dynamics on a single-particle level.
我们公开了一种从自发形成的空心糖 - 表面活性剂微管合成手性胶体的方法，这些微管内部含有受限的可移动胶体球。我们方法的关键特征是在胶体表面接枝光响应香豆素部分，这使得胶体能够通过紫外线诱导进行共价点击形成永久链，其形态由胶体与微管的直径比决定。随后去除微管限制得到水性悬浮液，其中包含大量各种线性链，包括聚苯乙烯胶体的单螺旋链。这些手性（DNA）分子的胶体等效物旨在用于单粒子水平上手性动力学的微观研究。
