Nanofabrication is one of the core techniques in rapidly evolving nanoscience and nanotechnology. Conventional top-down nanofabrication approaches such as photolithography and electron beam lithography can produce high-resolution nanostructures in a robust way. However, these methods usually involve multistep processing and sophisticated instruments and have difficulty in fabricating three-dimensional complex structures of multiple materials and reconfigurability. Recently, bottom-up techniques have emerged as promising alternatives to fabricating nanostructures via the assembly of individual building blocks. In comparison to top-down lithographical methods, bottom-up assembly features the on-demand construction of superstructures with controllable configurations at single-particle resolution. The size, shape, and composition of chemically synthesized building blocks can also be precisely tailored down to the atomic scale to fabricate multimaterial architectural structures of high flexibility. Many techniques have been reported to assemble individual nanoparticles into complex structures, such as self-assembly, DNA nanotechnology, patchy colloids, and optically controlled assembly. Among them, the optically controlled assembly has the advantages of remote control, site-specific manipulation of single components, applicability to a wide range of building blocks, and arbitrary configurations of the assembled structures.

光热组装纳米结构
纳米制造是快速发展的纳米科学和纳米技术的核心技术之一。传统的自上而下的纳米制造方法，例如光刻和电子束光刻，可以以稳健的方式产生高分辨率的纳米结构。然而，这些方法通常涉及多步骤处理和复杂的仪器，并且难以制造多种材料的三维复杂结构和可重构性。最近，自下而上的技术已经成为通过组装单个构建块来制造纳米结构的有前途的替代方案。与自上而下的光刻方法相比，自下而上的组装具有在单粒子分辨率下按需构建具有可控配置的上层结构的特点。化学合成构件的尺寸、形状和成分也可以精确定制到原子尺度，以制造具有高灵活性的多材料建筑结构。据报道，许多技术可将单个纳米粒子组装成复杂的结构，例如自组装、DNA 纳米技术、斑块胶体和光控组装。其中，光控装配具有远程控制、单个部件的定点操纵、适用于广泛的积木以及装配结构的任意配置等优点。
