The co‐assembly of spherical colloids and surfactant–cyclodextrin microtubes yields a library of dynamic colloid‐in‐tube structures, including helices. In situ observations of these structures, including their thermo‐reversible assembly and disassembly, demonstrate the potential of the interplay between molecular and colloidal self‐assembly, thereby providing a novel route to temperature‐sensitive particle alignment and release.

Hierarchical self‐assembly is often exploited by nature to build complex functional entities. A similar approach yielded a library of dynamic colloid‐in‐tube structures, such as colloidal zigzags, double‐ and triple‐helices, by utilizing the thermo‐reversible co‐assembly of colloidal spheres and molecular microtubes, as reported by J. Huang, A. V. Petukhov, et al. in their Communication on page 3364 ff. The assembly and disassembly of these structures near human body temperature was explored in situ and in real time.
