We report a strategy to assemble and manipulate nanoparticles arrays. The approach is based on the use of topological defects, namely disclination lines, created in chiral liquid crystals. The control of nanoparticle-loaded topological defects by low power light is demonstrated. Large-scale rotation, translation and deformation of quantum dots light-emitting chains is achieved by homogeneous LED illumination. Full reconfigurability and time stability make this approach attractive for future developments and applications.
我们报告了一种组装和操纵纳米颗粒阵列的策略。该方法基于在手性液晶中产生的拓扑缺陷，即向错线。展示了通过低功率光对负载纳米颗粒的拓扑缺陷的控制。通过均匀的发光二极管照明实现了量子点发光链的大规模旋转、平移和变形。完全可重构性和时间稳定性使该方法对未来的发展和应用具有吸引力。
