摘　　要：构筑具有特定功能的复杂物质是纳米颗粒自组装的重要目标之一。聚焦于纳米颗粒自组装的基本原则,讨论了纳米粒子间的相互作用力驱动自组装具有理想性能的纳米结构和材料,精确制备从零维到三维的高质量结构,如胶体分子、纳米链、胶体晶体和光子晶体等;回顾了2022年纳米颗粒组装体在传感、光电器件、显示、药物递送和生物医疗诊断领域所取得的重要进展,并提出了该领域在构筑新物质方面面临的挑战。Constructing complex matters with unique functions is one of the goals of nanoparticle self-assembly. In this article we review the basic principle of nanoparticles self-assembly and discuss the interactions between nanoparticles to regulate selfassembled structures and materials with desirable properties. Based on these principles, high quality structures from zero to three dimensions can be prepared such as colloidal molecules, nanochains, colloidal crystals and photonic crystals. We summarize the important advances of assembled structures in sensing, optoelectronic devices, display, drug delivery and biomedical diagnostics in 2020. Finally, we propose the challenges of building new substances in this field.
