通过表面模板自组装与瑞利不稳定性驱动的金纳米线断裂相结合，制备了负载金纳米粒子的超长圆柱形胶束。金纳米粒子可位于圆柱形胶束中心，其直径、粒子间距及嵌有金纳米粒子的圆柱直径可通过调节金纳米线浓度精细控制；不同条件下还观察到金纳米线向金纳米粒子转变的两种不同路径。该方法为杂化纳米材料的制备提供了一种非传统策略。

Ultralong cylindrical micelles impregnated with gold nanoparticles were fabricated via the convergence of a surface-templated self-assembly method and the fragmentation of gold nanowires driven by Rayleigh instability. The AuNPs could be located at the center of the cylindrical micelles, and their diameter, interparticle distance and the diameter of the cylinder embedded with AuNPs could be finely controlled by tuning the concentration of AuNWs. Two different pathways of AuNW-to-AuNP transformation in the hybrid micelles were observed under different conditions. This approach could be proposed as an unconventional method for the fabrication of hybrid nanomaterials.
