摘要

胶体纳米颗粒(NPs)的定向自组装是利用外场引导形成复杂的分层材料,但随着颗粒尺寸的减小,其效果也会减弱。作为一种替代方法,电子束驱动的组装为定向纳米操纵提供了一条潜在的途径,但由于电子束相互作用机制的多样性和复杂性,这种方法的可控性仍然很差。在这里,我们研究了钉在离子液体液滴的流体-真空界面上的二氧化硅 NPs 的光束-粒子相互作用。在这些实验中,液滴表面的扫描电子显微镜可以解析 NP 在空间和时间上的轨迹,同时驱动它们重组。利用这一平台,我们展示了引导粒子传输并在液滴表面形成瞬时、可逆胶体模式的能力。通过调节光束电压,我们实现了对光束与粒子相互作用的强度和符号的精确控制,低电压排斥粒子,高电压吸引粒子。总之,电子束引导组装为纳米尺度胶体操纵引入了一种多功能策略,为设计动态可重构系统提供了新的可能性,可应用于自适应光子学和催化等领域。

Reversible Electron-Beam Patterning of Colloidal Nanoparticles at Fluid Interfaces
The directed self-assembly of colloidal nanoparticles (NPs) using external fields guides the formation of sophisticated hierarchical materials but becomes less effective with decreasing particle size. As an alternative, electron-beam-driven assembly offers a potential avenue for targeted nanoscale manipulation, yet remains poorly controlled due to the variety and complexity of beam interaction mechanisms. Here, we investigate the beam-particle interaction of silica NPs pinned to the fluid-vacuum interface of ionic liquid droplets. In these experiments, scanning electron microscopy of the droplet surface resolves NP trajectories over space and time while simultaneously driving their reorganization. With this platform, we demonstrate the ability to direct particle transport and create transient, reversible colloidal patterns on the droplet surface. By tuning the beam voltage, we achieve precise control over both the strength and sign of the beam-particle interaction, with low voltages repelling particles and high voltages attracting them. This response stems from the formation of well-defined solvent flow fields generated from trace radiolysis of the ionic liquid, as determined through statistical analysis of single-particle trajectories under varying solvent composition. Altogether, electron-beam-guided assembly introduces a versatile strategy for nanoscale colloidal manipulation, offering new possibilities for the design of dynamic, reconfigurable systems with applications in adaptive photonics and catalysis.
