We report a strategy to assemble and manipulate nanoparticles arrays. The approach is based on theuse of topological defects, namely disclination lines, created in chiral liquid crystals. The control ofnanoparticle-loaded topological defects by low power light is demonstrated. Large-scale rotation,translation and deformation of quantum dots light-emitting chains is achieved by homogeneousLED illumination. Full reconfigurability and time stability make this approach attractive for futuredevelopments and applications.

Abstract
We report a strategy to assemble and manipulate nanoparticles arrays. The approach is based on theuse of topological defects, namely disclination lines, created in chiral liquid crystals. The control ofnanoparticle-loaded topological defects by low power light is demonstrated. Large-scale rotation,translation and deformation of quantum dots light-emitting chains is achieved by homogeneousLED illumination. Full reconfigurability and time stability make this approach attractive for futuredevelopments and applications.File in questo prodotto:
