纳米技术在构建功能器件，包括集成电路、透明电极和柔性致动器方面引起了广泛的研究关注。自底向上制造是功能结构制造的一种重要方法，然而，复杂结构的可控制造长期以来一直是一个挑战。本文提出了一种基于胶分子调制的激光等离子体激元制造新策略，可以将金属纳米晶体组装成互连的图案网络。纳米晶体的等离子体响应可以通过分子调制进行调节，这有利于激光诱导局域振荡电子的有效形成。分子的进一步分解和表面原子的运动可以实现组装纳米晶的聚结。它表明，复杂的结构可以可控地构建分子水平的调制。通过分子辅助激光等离子体制造，具有增强光热能力的功能纳米晶体可用于信息加密和软机械。这项工作扩展了自下而上制造的知识，并提供了一种为广泛的应用设计功能纳米晶体的方法。
Nanotechnology has attracted wide research attention in constructing functional devices, including integrated circuits, transparent electrodes, and flexible actuators. Bottom‐up fabrication is an important approach for functional structure manufacture, however, the controllable fabrication of complex architectures for practical applications has long been a challenge. Here, a novel strategy of laser plasmonic fabrication based on glue molecule modulation is proposed that can assemble metal nanocrystals into interconnected pattern networks. The plasmonic response of nanocrystals is adjustable with molecule modulation, which is a benefit for the effective formation of laser‐induced localized oscillating electrons. The further decomposition of molecules and the movement of nanocrystal surface atoms can achieve the coalescence of assembled nanocrystals. It demonstrates that complex architectures can be controllably constructed by molecule level modulation. Through molecule‐assisted laser plasmonic fabrication, the functional nanocrystals with enhanced photothermal capacity can be used for information encryption and soft machinery. This work expands the knowledge of bottom‐up fabrication and provides a method for designing functional nanocrystals for a wide range of applications.
