使用纳米材料作为构建块并具有Meta功能性来制造新材料的能力是材料设计和合成领域中最有趣的可能性之一。半导体量子点（QD）和磁性纳米颗粒（MNP）共分散在液晶（LC）矩阵和直接形成自相似组件，通过利用主机的热致相变。这些共组装体，包括6 nm的CdSe/ZnS QD和5-20 nm的Fe 3 O 4 MNP，桥接纳米至微米长度尺度，并且可以通过施加的磁场原位调制
The ability to fabricate new materials using nanomaterials as building blocks, and with meta functionalities, is one of the most intriguing possibilities in the area of materials design and synthesis. Semiconducting quantum dots (QDs) and magnetic nanoparticles (MNPs) are co-dispersed in a liquid crystalline (LC) matrix and directed to form self-similar assemblies by leveraging the host's thermotropic phase transition. These co-assemblies, comprising 6 nm CdSe/ZnS QDs and 5-20 nm Fe3O4 MNPs, bridge nano- to micron length scales, and can be modulated in situ by applied magnetic fields
